Ah! that perennial desire for eternity. The calculator uses solar power. It also have a battery. Under normal circumstances you won't need a battery, may be if you are living through a long Nuclear Winter.
Any way, just get a battery with the same characteristics as the one that shipped with the calculator: voltage, thickness, diameter. That is what counts.

SOURCE: Casio FX-115 ES: SIN,COS,TAN (answer isnt correct)

Hello,
It may be due to the angle unit used. You can have angles in degrees, in radians, and in grads. You should set the default angle unit to waht you problem calls for.
To set degree as default SHIFT MODE 3
To set radians as default SHIFT MODE 4
To set grads as default SHIFT MODE 5

The values of angles calculated by the inverse trigonometric functions are in the default unit that is set . This may be the source of the wrong answers that you get.

Hope it helps.

SOURCE: How I can memorize my

Sorry, but you cannot.
You can type in a formula that involves the memory variables X,Y, A, B,C,D, E, =, . Such a formula is meant to be evaluated to get a solution (X by default). Once you type the formula you press the Shifted function SOLVE and you will be prompted for the constants, for Y etc. when you press the EXE/= key you get the value of X.
If you turn off the calculator or change the calculation MODE, it is wiped out of memory.

To make a long story short, you cannot STORE formulas in the calculator. Better try to memorize them (commit then to YOUR OWN memory).

I have buy t-10 10 mega digital camera of olympus from home shop 18 but i am not much satisfied with detalis n features of camera like which kind of batteries are best for my camera ni-mh or alkaline or...


You must use good alkaline batteries or better, a set of high capacity NiMH rechargeables. Zinc or "long life" batteries just aren't up to the task, and they can leak and cause corrosion.

NiMH batteries with a capacity of 2700mAH are available, and these will last longer, per charge, than name brand alkalines, as well as being rechargeable. You can buy these with a charger fairly cheaply now (though they obviously cost more than disposables). You will probably want two sets, one to be on charge while you use the other.

Choosing batteries


Your camera requires four AA size batteries.There are several factors that contribute to battery life: NiMH: This is the best solution for enjoyment and cost savings. NiMH batteries typically last longer per charge than the average alkaline batteries. NiMH batteries are rechargeable batteries, so they can be used several times and thereby reduce the expense of continually purchasing new batteries. NiMH batteries are typically sold with a power adapter for charging. The life of these batteries can often be determined by the mAh rating, the higher the mAh rating on the battery, the longer that they will last. NiMH batteries do not have the memory effect associated with NiCd batteries, which means that these batteries can be recharged at any time and at your convenience (you do not have to wait for the batteries to completely drain between charges). Lithium: Energizer has introduced a new series of Lithium batteries that provide optimum performance and long life for disposable AA size batteries. Laboratory studies shows that Lithium batteries last more than three times as long as standard Alkaline batteries. This means many more hours of fun and satisfaction with your digital camera. These lithium batteries are not rechargeable, they are long lasting. Alkaline: Using the LCD display, downloading images, playback, zoom and flash all require some battery power to operate and may decrease the number of shots per set of batteries. Performance may also vary based on the Alkaline batteries selected. To significantly increase battery life, be sure to turn off the LCD when it is not in use. The LCD consumes the most amount of battery power. The benefit of being able to use alkaline batteries is that you can find then almost anywhere if needed. Manganese: If you are using manganese batteries, the typical battery life will be about 2 - 5 shots. Then the camera will indicate that battery power is low and may shut-down. To avoid this experience, use either Alkaline or NiMH batteries. Optimum Solution: Use a set of NiMH batteries for longer use and to reduce the expense of continually buying new batteries. It may also be a good idea to keep a spare set of NiMH batteries for other devices that require AA size batteries on a regular basis. Use AA Alkaline batteries when the NiMH batteries need to be recharged and you want to continue enjoying the use of your camera.
