To use the inverse buttons, typically you will need to press a button labeled 2 nd on your calculator and then the sin, cos or tan button. This produces sin-1 on the calculator screen. Many of the calculator companies have on-line tutorials if you need more help, including TI, Sharp, and HP. Why does it work? Three similar triangles. Angle c is the same in each case and so is the tangent of c... For either the graphic solution or the algebraic solution it is important to realize that cos 2 x = (cos x)(cos x) = (cos x) 2. To enter cos 2 x into your calculator, calculate cos x and square it. For an algebraic solution write y = cos x and then the equation becomes 2 y 2 - 3 y - 4 = 0.

- 5/04/2009Â Â· On paper cos^2(33) would be the same as cos(33)*cos(33) but cos(33)^2 would be the same as cos(33*33). On a calculator though, it should be written as (cos(33))^2 or do cos(33) then hit enter and then Ans^2.
