WebThe cosine double angle formula tells us that cos (2θ) is always equal to cos²θ-sin²θ. For example, cos (60) is equal to cos² (30)-sin² (30). We can use this identity to rewrite … WebSo, in order for this substitution to work out okay, you're letting x=a*tan(theta) so that when you write it out, you will end up with a^2+(a*tan(theta))^2 in your denominator. Simplifying leads to a^2+(a^2 * tan^2(theta)), and factoring the a^2 out gets: a^2(1+tan^2(theta)).

WebJun 9, 2016 · y^2 = 49 - 16 = 33. y = ±√33. Because theta is in QII, y = +√33. sin (theta) = y/r = √33/7. To solve for csc (theta) realize that csc (theta) = 1/sin (theta). csc (theta) = 1/ (√33/7) = 7/√33. You must radicalize the denominator. 7/√33 * √33/√33 = 7*√33/33. WebD. $2.25.
