Question

Find two solutions to the equation. Give your answers in degrees (0° ≤ 𝜃 < 360°) and radians (0 ≤ 𝜃 < 2𝜋). Enter your answers as comma-separated lists.)

(a)    cot(𝜃) = 0

degrees

radians

(b) sec(𝜃)= - square root 2

degrees

radians

Answer 1

cotT=0

T=pi/2, 3pi/2

or 90, 270 degrees

secT=-sqr2

T=3pi/4, 5pi/4

or 135, 225 degrees
