Verify the Identity:
Sin(cot+tan)=sec
I got :
Sincot+sintan
Sin/1 (1/tan)+sin/1(Sin/cos)
1/sintan+sin/sincos
^(the bottom of 1/sintan) Simplified to sin/1(sin/cos) Then it canceled out and the Sin/sincos simplified to sec and it was verified. Is this right ?

anonymous · Answer

cot x = cosx/sinx

tanx = sinx / cosx

Use this

anonymous · Answer

Sin ( (sin^2 + cos^2)/sinx cos x) =  secx
