Prove the trig identity: cot(theta)sec(theta)sin(theta) = 1?
- Anonymous9 years agoFavorite Answer
LHS = cot(θ)sec(θ)sin(θ)
= cos(θ)/sin(θ) * 1/cos(θ) * sin(θ)
I hope this helps!Source(s): Knowledge

a million+tan^2 (x) = sec^2 (x) write tan in terms of sin/cos and set undemanding denominator cos^2 x/cos^2 x + sin^2 x/cos^2 x = sec^2 x upload fractions (cos^2 x+ sin^2 x)/cos^2 x = sec^2 x use sin^2 + cos ^2 identity a million/cos^2 x = sec^2 x definition of sec sec^2 x = sec^2 x

Multiply the cotangent and secant's identities to find:
Now multiply sine's identity by the product to cancel out the sines.
