How to turn cos into csc

http://www.math.com/tables/trig/identities.htm WebWith only the sides given, you'd have to solve for an angle using the law of cosines. If the triangle had a right angle, you could use the inverse trig functions. The law of cosines is: c^2 = a^2 + b^2 - 2*a*c*cos(C) a, b, and c are sides of a triangle, and C is the angle …

Sec, Cosec and Cot – Mathematics A-Level Revision

WebFirst we apply the sum formula, cos (a+b) = cos (a) * cos (b) - sin (a) * sin (b): cos (2*phi) = cos (phi + phi) = cos (phi) * cos (phi) - sin (phi) * sin (phi) 2. Now you can see that you are multiplying cos (phi) by itself and sin (phi) by itself. So, cos (phi) * cos (phi) - sin (phi) * sin (phi) = cos^2 (phi) - sin^2 (phi) WebDO : Using the reciprocal trig relationships to turn the secant into a function of sine and/or cosine, and also use the derivatives of sine and/or cosine, to find d d x sec x.
