Deriving the Derivative Formulas for Tangent, Cotangent, Secant, Cosecant
Many people memorize these formula but do not really understand where they come from. I show how you just use the derivative formulas for sine and cosine along with the quotient rule and chain rule to derive the rest!
Deriving the Derivative of y = arctan (x)
In this video, I show how to derive the derivative formula for y = arctan(x). This is a super useful procedure to remember as this is how many of the inverse derivative formulas are derived! All we need to do is use implicit differentiation and some trig identities.
