The radical x 2 − 4 suggests a triangle with hypotenuse of length x and base of length 2 : For this triangle, sec θ = x 2, we will try the substitution x = 2 sec θ. Then θ = sec − 1 ( x 2), where we ...

WebAlternatively know that cos theta = x, sin theta = y, tan theta = y/x and then you could figure out where each trigonometric function is positive based on y and x values in the unit circle. So in the 4 quadrant since x is positive …
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 … the tap bar wareWebThe idea behind this substitution is to "cancel out" part of the denominator with the differential term (dx (dx in terms of d\theta) dθ) in order to integrate a smaller expression. When applied properly, something will cancel out, since \tfrac {dx} {d\theta} = 1 + x^2, dθdx = 1+x2, where x = \tan\theta x = tanθ.

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. serial you online
