Question 945283
what is the exact value of each of the following trigonometric functions of theta cos theta = -6/7 , pi less than 0 less than 3pi/2
***
cosx=-6/7 (&#960;,3&#960;/2) (1n quadrant III where sin<0, cos<0)
sinx=-&#8730;(1-cos^2(x))=-&#8730;(1-36/49)=-&#8730;(13/49)=-&#8730;13/7
secx=-7/6
cscx=-7/&#8730;13=-7&#8730;13/13
tanx=sin/cos=&#8730;13/6
cotx=6/&#8730;13=6&#8730;13/13
