x = asin∂

Whats the derivative of arcsin(x)

1/ √(1-x²)

Whats the derivative of arctan(x)

1/(x²+1)

tan²x = In terms of sec²x and 1

tan²x = sec²x-1

ln(1) = ??

0

a² + x²

x = atan∂

x² - a²

x= asec∂

∫ tanxdx

ln(sec(x)) + C

∫secxdx

ln(sec(x) + tan(x)) + C

sec²x= In terms of tan²x and 1

sec²x= tan²x + 1
