Is this a joke or what?
cos(30 deg)-cos(40 deg)=0.0999809607
sin(30 deg)+sin(40 deg)=1.14278761

And even if your functions are hyperbolic functions
the first expression cannot give 0 otherwise 30 would be equal to 40, and no reasonable person would expect that.

sinh(30)+sinh(40)=1.176979767 x 10^17

The trigonometric functions of my casio are all wrong example: tan45=0,85 sin30=0,45399


Your calculator is set the measure angles in grads. To change this, press the MODE button one or more times until you see a line saying "Deg Rad Gra". Press 1 to select degrees or 2 to select radians.

What is the value of SIN15 degree and COS15 degree.....?


Hi rowanwah

The sine of an angle is only applicable is a right triangle. If you just want a number, ie, the actual value of the sine 15 degrees you can look it up on Google. Do a search for "sine and cosine functions"

If you want the mathematical description of the sine of an angle it is described as follows
In a triangle ABC, there are 3 angles angle A, angle B and angle C. There are also 3 sides, Side AB, Side AC and side BC. The sine of angle A is equal to the side opposite Angle A divided by the Hypotenuse (the longest side opposite the right angle)
The Cosine of angle A is equal to the side adjacent to Angle A divided by the hypotenuse

Hope this helps Loringh PS Please leave a rating for me Thanks
