Assume that is an angle in standard position whose terminal
Assume that is an angle in standard position whose terminal side contains the point (24,7). Find the exact values of the following functions.
sin=
cos=
tan=
cot=
sec=
csc=
Solution
Point ( 24, 7) in coordinate plane in Ist coordiante
All trig ratios would be +ve
Now sinx = height/ hypotenuse
Hypotenuse = ssqrt( 24^2 +7^2) = 25
sinx = 7/25
cosx = base/hypotensues = 24/25
tanx = height/base = 7/24
secx = 1/cosx = 25/24
cscx = 1/sinx = 25/7
cotx = 1/tanx = 24/7
