Cosx sinx identity
WebTo convert sin x + cos x into sine expression we will be making use of trigonometric identities. Using pythagorean identity, sin 2 x + cos 2 x = 1. So, cos 2 x = 1 - sin 2 x. By taking square root on both the sides, cosx + sinx = sinx ± √1 - sin 2 x. Using complement or cofunction identity, cosx = sin(π/2 - x) sinx + cosx = sinx + sin(π/2 - x) Web5. prove this:]sin x/ sin x + cos x / sinx -cos x/ cos x - sinx / cos x =secx csc x Note that i made it (+) sinx/cosx because otherwise, it won't be equal. Double check if your plus/minus signs are correct :)
