Question 20

deg to rad

Answer 20

0 - 0
30 - pi/6
45 - pi/4
60 - pi/3
90 - pi/2

Question 21

sin and cos cofunctions

Answer 21

sin theta = cos (pi/2 - theta)
cos theta = sin (pi/2 - theta)

Question 22

tan and cot cofunctions

Answer 22

tan theta = cot (pi/2 - theta)
cot theta = tan (pi/2 - theta)

Question 23

sec and csc cofunctions

Answer 23

sec theta = csc (pi/2 - theta)
csc theta = sec (pi/2 - theta)

Question 24

conversion between deg and rad

Answer 24

pi/ 180 or 180/ pi

Question 25

trig identities

Answer 25

1 + cot^2 theta = csc^2 theta
1 + tan^2 theta = sec^2 theta
sin^2 theta + cos^2 theta = 1
