Question

PLEASE HELP If cos(x)=sqrt(10)/10 fin csc(x)

Answer 1

find sec*

Answer 2

\[\cos(x)=\frac{\sqrt{10}}{10}\]
sec?
sec is just the reciprocal of sqrt(10)/10

Answer 3

if cos(x)=a/b then sec(x)=b/a
if sin(x)=c/d then csc(x)=d/c
if tan(x)=p/q then cot(x)=q/p
by the way these if statements can also go the other away around

Answer 4

Use the pythagorean theorem to find the other side, so you can get the secant of x.

Answer 5

ok thanks
