If ##tan (x) =5/12##, then what is sin x and cos x?
February 20th, 2023
Viewed as a right angled triangle
##tan(x)=5/12##
can be thought of as the ratio of opposite to adjacent sides in a triangle with sides ##5, 12## and ##13## (where ##13## is derived from the Pythagorean Theorem)
So
##sin(x) = 5/13##
and
##cos(x) = 12/13##
