In triangleABC,

Cotangent

Example3:Find the secant,cosecant,and cotangentof angleB.

Solution:

First,we mustfind the lengthof the hypotenuse.We can do this usingthe PythagoreanTheorem:

52 + 12^2 =H^2

=H

25 + 144^2

=H

169 2

H = 13

Now we can find the secant,cosecant,and cotangentof angleB:
