LIMITS OF TRIGONOMETRIC FUNCTIONS

 

 

The following equations are valid only when q is measured in radians

 

 

 
 

                      (if θ is measured in degrees)

 
 

 
 

 
 

 
 

 
 

 

 

 

 

 

DERIVATIVE OF TRIGONOMETRIC FUNCTIONS:

 

The following equations are valid only when q is measured in radians

 

 

 

u = f(x)

 

 

(sin u) = (cos u) u’

 

 

 

(cos u) = - (sin u) u’

 

 

(tan u) = (sec2 u) u’

 

(secant:  sec u =)
