The chain rule is used to differentiate any composite function of the form y = f (g (𝑥)). That is a function that has an inner function with an outer function applied to it. For example y = (3𝑥 + 2)5 is made of the functions g (𝑥) = 3𝑥 + 2 and f (𝑥) = 𝑥5.
The function f(x) = [exp(x) + exp( x)]=2 is called cosh(x). The function f(x) = [exp(x) exp( x)]=2 is called sinh(x). They are called hyperbolic cosine and hyperbolic sine.
Example: Find the derivative of 1=sin(x) using the quotient rule. Solution cos(x) 1=sin 2 (x). Example: Find the derivative of f(x) = 1=sin(x) using the chain rule.
The Law of Sines (or Sine Rule) is very useful for solving triangles: a sin A = b sin B = c sin C. It works for any triangle: And it says that: When we divide side a by the sine of angle A. it is equal to side b divided by the sine of angle B, and also equal to side c divided by the sine of angle C. Sure ... ?
Sine and Cosine Rules. Application: Area of Any Triangle. Heron's Formula. Sine Rule and Cosine Rule. 1 Sine and Cosine Rules. In the triangle ABC, the side opposite angle A has length a, the side opposite angle B has length b and the side opposite angle C has length c. The sine rule states. A. sin A sin B sin C. = = b c. C. a. B.
