Write in terms of the cofunction of a complementary angle sec 62 degrees
wrong again!
Cofunction(sec 62°) = csc 28°
Apologies for the mistake. You are correct.
The cofunction of sec 62 degrees is equal to the cosecant function of the complementary angle (csc 28 degrees):
Cofunction(sec 62 degrees) = csc 28 degrees
The cofunction of an angle is the trigonometric function of the complementary angle.
The complementary angle of 62 degrees is 90 - 62 = 28 degrees.
The secant function of an angle is equal to the reciprocal of the cosine function of that angle. Therefore, the cofunction of sec 62 degrees is equal to the reciprocal of the cosine function of the complementary angle (cos 28 degrees):
Cofunction(sec 62 degrees) = 1 / cos 28 degrees
