Question

The point P(8, 6) is on the terminal side of θ. Evaluate sin θ.

someone explain it becuase i dont understand one bit

Answer 1

hmmm I got them backwards...

Answer 2

ok

Answer 3

use the pythagorean theorem to find the hypotenuse, then use your soh cah toa, to get the sine function http://www.mathwarehouse.com/trigonometry/images/sohcohtoa/sohcahtoa-all.png

Answer 4

i dont understand how to use the pythagorean theorem

Answer 5

hmm well, do you know the pythagorean theorem?

Answer 6

yes a little

Answer 7

tan 6/8 right

Answer 8

\(\bf c^2=a^2+b^2\implies c=\sqrt{a^2+b^2}\) once you found "c" side, then use that to get the sine function \(\bf sin(\theta)=\cfrac{opposite}{hypotenuse}\implies \cfrac{b}{c}\)
