Assume that 0 is an angle in standard position whose terminal side contains the point (5,12).

Find the exact values of the following functions.

sin0=

csc0=

sec0=

cot0=

solution -: In the terminal side we have opposite side = -12 and adjacent side = -5

we will find hypotenuse by using pythagoras thoerem

c^2 = a^2+b^2 here a= -12 and b= -5

c^2 = (-12)^2 + ( -5)^2 =144+25 = 169

c= sqrt(169)= 13

It is in third quadrant

sinO= -12/13

cscO= -13/12

secO = -5/13

cotO = -5/-12 = 5/12 answers
