How to solve for tan 2 theta
WebStart by simplifying the tan^2 theta angle tan^2 = sin^2+cos^2 = 1 << this we can agree on the solutions tell us to divide both sides by cos^2. so sin^2/cos^2 + cos^2/cos^2 = 1/cos^2 and 1/cos^2 is sec^2 << still … WebStart with the RHS (tan (pi/4 + theta/2) and use the tan (A+B) formula to simplify. Next transform tan (theta/2) using tan theta = sin theta/ cos theta for theta/2. Rationalise the …
