45 - pi/4
60 - pi/3
90 - pi/2
21
Q
sin and cos cofunctions
A
sin theta = cos (pi/2 - theta)
cos theta = sin (pi/2 - theta)
22
Q
tan and cot cofunctions
A
tan theta = cot (pi/2 - theta)
cot theta = tan (pi/2 - theta)
23
Q
sec and csc cofunctions
A
sec theta = csc (pi/2 - theta)
csc theta = sec (pi/2 - theta)
24
Q
conversion between deg and rad
A
pi/ 180 or 180/ pi
25
Q
trig identities
A
1 + cot^2 theta = csc^2 theta
1 + tan^2 theta = sec^2 theta
sin^2 theta + cos^2 theta = 1
