You can see the Pythagorean-Thereom relationship clearly if you consider the unit circle, where the angle is t, the "opposite" side is sin(t) = y, the "adjacent" side is cos(t) = x, and the hypotenuse is 1.
How do you prove #1 + cot² x = csc² x#? - Socratic.org
WebDec 18, 2024 · Simplify cot^2 (x) - csc^2 (-x) This was a multiple choice question, the answer i got was 1, but apparently the answer was -1, how could this be since csc^2 (-x) = -csc^2x which would turn the subtraction into positive? Follow • 2. Add comment. Report. WebJul 22, 2015 · Explanation: cot2x +cscx = 1. Use the identity : cos2x +sin2x = 1. ⇒ cot2x +1 = csc2x. ⇒ cot2x = csc2x − 1. Substitute this in the original equation, csc2x −1 +cscx = 1. ⇒ csc2x +cscx − 2 = 0. This a quadratic equation in the variable cscx So You can apply the quadratic formula, how to split drives in laptop windows 11

WebJun 1, 2016 · 1 + cot2θ = csc2θ. We can substitute csc2θ directly into the second term but need to do a bit of math to get the substitution for the first term: sin2θ+ cos2θ = 1. sin2θ = 1 −cos2θ. Now let's substitute: (1 −cos2θ)(1 +cot2θ) (sin2θ)(csc2θ) The relationship between sin and csc is: csc = 1 sin. WebThe Pythagorean Identities are based on the properties of a right triangle. cos2θ + sin2θ = 1. 1 + cot2θ = csc2θ. 1 + tan2θ = sec2θ. The even-odd identities relate the value of a trigonometric function at a given angle to the value of the function at the opposite angle. tan(− θ) = − tanθ. cot(− θ) = − cotθ. WebAug 7, 2013 · cos^2 x + sin^2 x = 1. sin x/cos x = tan x.
