Question

find the trigonometric functions of 240​

Answer 1

Step-by-step explanation:

There is another way, using the trig unit circle.

• sin240=sin(60+180)=−sin60=−sqr32 (trig table)
• cos240=cos(60+180)=−cos60=−12.
• tan240=sin240cos240=sqr3.
• cot240==1sqr3=sqr33.
• sec240=1sin240=−2sqr33.
• csc240=1cos240=−2.

There is another way, using the trig unit circle.

sin240=sin(60+180)=−sin60=−sqr32 (trig table)

cos240=cos(60+180)=−cos60=−12.

tan240=sin240cos240=sqr3.

cot240==1sqr3=sqr33.

sec240=1sin240=−2sqr33.

csc240=1cos240=−2.
