Tan from cos and sin
WebSep 17, 2024 · There are perfectly good reasons why you might be interested in allowing for any angle between -pi and pi. It's just that, if you don't make the -pi/2,pi/2 restriction then MATLAB won't recognize that atan2(sin(alpha),cos(alpha))=alpha. Under your assumption that alpha is between -pi and pi, it should recognize that, but for some reason it doesn't. Web1.5 sin θ = cos θ. Squaring both sides we have. 2.25 sin 2 θ = cos 2 θ. and since cos 2 θ = 1 − sin 2 θ we have. 2.25 sin 2 θ = 1 − sin 2 θ 2.25 sin 2 θ + sin 2 θ = 1 3.25 sin 2 θ = 1. From this, you can figure out the value of sin 2 θ. Taking square roots will tell you something about the absolute value of sin θ.
