Question

Will MEDAL
Cos(sin2/3 + tan3/2)
Sum and Difference Formula
Can someone do this problem and tell me what they get so I can compare it with my own

Answer 1

so.. we're dealing with \[\cos(\theta+ \beta) \]
where \[\theta = \sin \frac{2}{3}, \beta = \tan \frac{3}{2}\] ?

Answer 2

\[\cos( \theta+ \beta) = \cos(\theta)\cos(\beta)-\sin(\theta)\sin(\beta)\]

Answer 3

if my beta is tangent then I have to find cosine and sine of my beta
