Please see below. sin-1 is used when you are trying to find the Angle that corresponds to a given Sine. sin( ) is used when you are trying to find the Sine of a given angle

Apr 28, 2015 · In sin-1 x, the "-1" is NOT an exponent. It represents the inverse of the sine function. Recall f(x) and f-1 (x).

Dec 27, 2018 · No, (1 / sin x) = csc x This identity should be memorized. arcsin is the inverse relation of the sin. E.g., sin 30° = 0.5

Dec 3, 2014 · Cos/1+sin + 1+sin/cos = 2sec , and cos = 0.866025, sin = 0.500, tan = sin/cos = 0.57735, and sec = 1/cos ...

Jan 13, 2017 · 1+sin2x = 1+2sinxcosx = sin^2x + cos^2x + 2sinxcosx = (sinx + cosx)^2 = an alternate way of expressing 1+sin2x -> if this is what you were looking for.

Oct 11, 2012 · first, Simplify 1- cos 2 Θ= sin 2 Θ. We know the expression a 2 - b 2 = (a+b)( a- b). Similarly, write the left hand side of the equation as (1+cos Θ)(1-cos Θ)
