Practice problem
Simplify until you reach a single trig function: 2tanasin2a+cos2a+sec2a−1\frac{2\tan a}{\sin ^{2}a +\cos^{2}a +\sec^{2}a -1}sin2a+cos2a+sec2a−12tana
sin(2a)\sin(2a)sin(2a)
cos(2a)\cos(2a)cos(2a)
tan(2a)\tan(2a)tan(2a)
sin(a)\sin(a)sin(a)
Type a concept, like “slope” or “photosynthesis”.
