I assume that if you want to input the equation it is with the intent to solve it. If that be the case then what follows will help you input and solve any equation (linear, quadratic, trig, etc.)

Make sure the calculator angle unit is the same as your problem requires (degree, radian, grad). Here are some screen capture to help you. Change the equation to yours.

To enter the equation in screen above, use the right arrow.

You
have to enter an initial guess on line X=, a default value may be
supplied by calculator: It depends on last value stored in X. Once a
value is entered press the Fhow to input cos x=0.75? - a5b0f3e.jpgLV

Press F1: Rept if you want to solve another equation.

X = Cones

Y = Sundaes

X + Y = 182 --- Y = 182 - X

0.90 * X +1.65 * y = 226,05

0,90 * X + 1,65 ( 182 - X) = 226,05

0.90 * X + 1,65 * 182 - 1.65 X = 226.05

300.3 - 226,05 = 1,65 x - 0,9 x = 0,75 X

74,25 / 0,75 = X

X = 99

y = 83

Y = Sundaes

X + Y = 182 --- Y = 182 - X

0.90 * X +1.65 * y = 226,05

0.90 * X + 1,65 * 182 - 1.65 X = 226.05

Secant is the reciprocal of cosine

**sec(x)=1/cos(x)**

Do not confuse it with the inverse of the cosine function, which is** arccos(x) =cos^-1(x) **

Do not confuse it with the inverse of the cosine function, which is

Gemma,

You won't need a calculator for this. The cosine of 'a' + 'b' is a semi-important math identity:

1. Cos(A+B) = cos(A)*cos(B) - sin(A)*sin(B)

2. Sin(A+B) = sin(A)*cos(B) + sin(B)*cos(A)

Taddahh!

Ofcourse, you could just take the sum of A & B and throw that value into cosines input; but then you would be setting yourself back when it comes time to learn the closely related double-angle identities (which are more important).

Arrivederci,

Press "Mode"
Check to see if you are in radian mode or degree mode (one of the top categories)

If you are entering your numbers from sin, cos, and tan as degrees and you are in radians, your answers will be off. Same goes for if you are inputting radians while in degree mode. Hope this helps

here are the steps in changing it from radian to degrees

1. turn on your TI-83 plus

2. press the MODE button near the top of your calculator

3.go down to options and move the highlight from radian to degree, press enter and clear

you're good to go
