Question

Sin 2 theta is equal to

Answer 1

Step-by-step explanation:

Sin 2 theta is the sine of the angle which is double the value of theta. This can be used when you know the value of sine and cosine of theta and not 2 theta. How do I show that tan theta=4/3 or tan theta=2m/m^2-1 if (m+2) sin theta+(2m-1) cos theta=2m+1?

I hope this may help you
