# Thread: BASIC Grade 11 Trigonometry Question on tan, cosec, sec, cot

1. ## BASIC Grade 11 Trigonometry Question on tan, cosec, sec, cot

The question I don't get is:

"For which of the trigonometric points defined in the previous question is it impossible to calculate:

a) the tangent?
b) the cosecant?
c) the secant?
d) the cotangent?"

the previous question was:

"Without using a calculator, give the coordinats of the trigonometric point corresponding to a central angle that measures"

a) 0°
b) -90°
c) 180°
d) -270°
e) -360°"

Any help would be GREATLY appreciated!
Thanks!

2. Go ahead and calculate them all at those locations. Which ones have a zero in the bottom and are thus impossible to calculate?
