Hi, I know when doing trigonometry that if the if a side is at the bottom of ten equation so AB\8 =sin 60 that you would times the 8 by sin 60 but what would you do if the unknown is at the bottom? Sorry if it's too vague
Hey is it possible for you to help me with this question?
(b) By writing the following equation as quadratics in tan θ/2, solve, in the interval 0 ≤ θ ≤ 360°:
(i) sinθ + 2cosθ = 1
Well you would first work out what θ equals by using the trigonometric equations, then you would substitute θ into tan θ/2 to get the angle. I assume that is what you would do anyways, been a while since I've done trig.
