sin 2 theta cos 2theta

sin 2 theta cos 2theta How do you simplify cos 2 theta 2 sin 2 theta 2 How do you find the exact value of cos2x using the double angle formula given cosx 2 13 pi 2

The Pythagorean identity states that sin 2theta cos 2theta 1 We can rearrange the identity to see that cos 2theta 1 sin 2theta If we know that cos 2theta 1 sin 2theta we can replace cos 2theta with 1 sin 2theta in the expression cos 2theta sin 2theta Simultaneous equation Differentiation Integration Limits Solve your math problems using our free math solver with step by step solutions Our math solver supports basic math pre algebra algebra trigonometry calculus and more

Here s an alternate answer Recall the identity sin 2theta cos 2theta 1 If you rearrange for cos 2theta you should get cos 2theta 1 sin 2theta Substituting we have sin 2theta 1 sin 2theta 0 sin 2theta 1 sin 2theta 0 2sin 2theta 1 sin 2theta 1 2 sintheta 1 sqrt 2 Now consider the 1 1 In the spirit of Git Gud s answer differentiate sin 2 theta cos 2 theta to get 2 sin theta cos theta 2 cos theta sin theta 0 So sin 2 theta cos 2 theta is constant Plugging in theta 0 shows that constant is 1
