Question

Simplify:
sinx+(cosx)(tanx)
Please explain...

Answer 1

\[\sin x+(\cos x)(\tan x)=\sin x+(\cos x)(\frac{\sin x}{\cos x})=2\sin x\]

Answer 2

Cancel and combine like terms.

Answer 3

then what about this one? (cscθ)(cosθ)(tanθ)?
I'm stuck at \[\frac{ \cos ^{2} }{\sin ^{2} } \]

Answer 4

That looks pretty close to \[\tan^2 \theta\]to me, but I don't see how you got it.\[ (\cscθ)(\cosθ)(\tanθ)= (\frac{1}{\sin \theta})(\cosθ)(\frac{\sin \theta}{\cos \theta})=1\]

Answer 5

You need to ramp up your attention to detail if you are going to be any good at trig.

Answer 6

Thanks!

Answer 7

No sweat. Do math every day.
