Re: Prove the trig identity cosx/(secx+tanx)= 1-sinx Murray 30 Dec 2015, 03:12 When you see a mix of trigonometric ratios, try converting everything to just sin, cos and/or tan.Re: Prove the trig identity cosx/(secx+tanx)= 1-sinx Alexandra 31 Dec 2015, 04:08 LHS=cos...
Verify the identity: cot x + 1 = csc x (cos x + sin x) Verify the identity: cot^2 x / csc x + 1 = 1 - sin x / sin x. Verify the identity. sin x + sin x cot^2 x = csc x Verify the identity. {cos (u) sec (u)} / {tan (u)} = cot (u) Verify the identity:...
