Hyperbolic Trig Identities Solved Problems Lesson Summary Frequently Asked Questions What is cosh and sinh? Cosh(x) and sinh(x) are the base hyperbolic trig functions. They are similar to cos(x) and sin(x) except they relate an area in a hyperbola to an x or y coordinate instead of re...
Use the definition of cotangent to find the known sides of the unit circle right triangle. The quadrant determines the sign on each of the values.Step 3 Find the hypotenuse of the unit circle triangle. Since the opposite and adjacent sides are known, use the Pythagorean theorem to find the...
2 Cos2X + 2 Sin X Cos X = 0 2 Cos X is common to both terms so this can be re-written: 2 Cos X ( Cos X + Sin X) = 0 This equation gives 0 if either 2 Cos X = 0 or Cos X + Sin X = 0. In other words: Cos X = 0orSin X = -Cos X The first equation gives ...

Then by the definition of inverse cos, cos y = x. Differentiating both sides with respect to x,-sin y (dy/dx) = 1dy/dx = 1/(-sin y) = -1/sin y ... (1)By one of the trigonometric identities, sin2y + cos2y = 1. From this, sin y = √1-cos²y = √1-x²....
