Find the values of $\theta$ in degrees $\left( 0 ^ { \circ } \leq \theta \leq 90 ^ { \circ } \right)$ and radians $\left( 0

Question

Find the values of

\theta

in degrees

\left( 0 ^ { \circ } \leq \theta \leq 90 ^ { \circ } \right)

and radians

\left( 0 < \theta < \frac { \pi } { 2 } \right)

without the aid of a calculator. cos

\theta

= 0 and tan

\theta

= Not defined

A)90° = $\frac { \pi } { 2 }$
B) 60° = $\frac { \pi } { 3 }$
C) 0° = 0
D) 30° = $\frac { \pi } { 6 }$
E) 45° = $\frac { \pi } { 4 }$

The cosine of an angle is 0 at $\theta = 90^\circ$ or $\theta = \frac{\pi}{2}$ radians, and the tangent is not defined at the same angles, which corresponds to the vertical line on the unit circle where the x-coordinate is 0.
