## Help!

can anyone verify my answer for this? Please and thank you.

**Evaluate the other five trigonometric functions given that:**

**cos (angle) = -**√**2/2 given that: pi/2<(angle),3pi/2**

**This is what i got:**

sin (angle) = + or - √2/2

tan (angle) = + or - 1

csc (angle) = + or - √2

sec (angle) = -√2

cot (angle) = + or - 1

**Find two coterminal angles for each angle; one positive and one negative.**

**-425 (degrees)**

**This is what i got:**

-425 + 360 = -65 (degrees)

-425 - 360 = -785 (degrees)

Thank you!!

these are incorrect. (your signs are off. you must have either + or -, not both).

Hint: what quadrant is the angle in?

**Find two coterminal angles for each angle; one positive and one negative.**

**-425 (degrees)**

**This is what i got:**

-425 + 360 = -65 (degrees)

-425 - 360 = -785 (degrees)

Thank you!!
