Question
it says to verify the following identity, working only on one side:
cotx+tanx=cscx*secx
Work the left side.
cot x + tan x = cos x/sin x + sin x/cos x
= (cos^2 x +sin^2x)/(sin x cos x)
= 1/(sin x cos x)
= 1/sin x * 1/cos x
You're almost there.
thanks so much! i could not figure that one out!
but i did now, lol.
cotx+tanx=cscx*secx
Work the left side.
cot x + tan x = cos x/sin x + sin x/cos x
= (cos^2 x +sin^2x)/(sin x cos x)
= 1/(sin x cos x)
= 1/sin x * 1/cos x
You're almost there.
