List of trig derivatives
Original | Derivative |
sinx | cosx |
cosx | -sinx |
tanx | sec²x |
cotx | -csc²x |
secx | secxtanx |
cscx | -cscxcotx |
Memory tricks:
-All the derivatives with c have a negative value (cosine, cotangent, and cosecant).
-Sine and cosine are best friends in calculus.
-Tangent and secant are best friends in calculus
