Jan 13, 2013 · 2 One well known tangent half-angle formula says $$ \tan\frac x2 = \frac {\sin x} {1+\cos x}. $$ Another well known tangent half-angle formula says: $$ \tan\frac x2 = \frac {1-\cos x} {\sin x}..
Jul 24, 2016 · I am doing a trig problem involving half-angle identities, and I am not sure if my solution is correct. Can someone please check my work? The question: Find the exact value of $\tan\frac {7\pi} {.
Imagine the case where $\theta$ is a large acute angle, like $89^\circ$. Then $\tan\theta$ is big, but $\tan\frac {\theta} {2}<1$

Jan 25, 2023 · The double angle formula for $\tan (x)$ is as follows: $$\tan (2x) = \frac {2\tan (x)} {1-\tan^2 (x)}$$ I wanted to see if I could solve this equation for $\tan (x)$ —I figured that I could.
Dec 22, 2011 · Double angle formulas The Double Angle formulas for $\sin$ and $\cos$ are derived by using the Sum and Difference formulas by writing, for example $\cos (2\theta)=\cos (\theta+\theta)$.
May 22, 2022 · Unlike the laws of sines, cosines and tangents, which are very well known, the half-angle formulas seem (although they appear timidly in the mathematical literature) not to enjoy the same.
Apr 3, 2011 · Using angle sum-difference, double, and/or triple angle relations with tangent, cosine, and sine, need help proving tangent half-angle relations. Thanks!
