A2 c2 b2 c2 c2 c2 This can be simplified to a c 2 b c 2 1 a c is Opposite Hypotenuse which is sin b c is Adjacent Hypotenuse which is cos So a c 2 b c 2 1 can also be written sin 2 cos 2 1 Note sin2 means to find the sine of then square the result but Cos 2 x sin 2 x 1 sin x cos x tan x You want to simplify an equation down so you can use one of the trig identities to simplify your answer even more some other identities you will learn later include cos x sin x cot x 1 tan 2 x sec 2 x 1 cot 2 x csc 2 x hope this helped

what is cos x formula - As we already know that cos 2X cos2 X sin2 X cos 2X 1 sin2 X sin2 X Since cos2 X 1 sin2 X cos 2X 1 sin2 X sin2 X So cos 2X 1 sin2 X sin2 X Hence cos 2X 1 2sin2 X cos 2X 2cos2 X 1 To derive this we need to start from the earlier derivation As we already know that cos 2X cos2 X sin2 X
