  1. Finding Trig Values from an x-y coordinate Find the 6 Trig functions for the angle that is formed by a terminal side passing through (2,4) y We know that trig values involve opposite, hypotenuse, and adjacent x These come from a right triangle so we need to create one

  2. Finding Trig Values from an x-y coordinate We make a right triangle by drawing a line from the point straight down (or up) to the x-axis This makes a right triangle y The vertical side is as long as the y-coordinate x The horizontal side is as long as the x-coordinate

  3. Finding Trig Values from an x-y coordinate The angle is in corner by the origin (0,0) so that makes 4 the opposite and 2 the adjacent We find the 3rd side by using y x So the hypotenuse is

  4. Finding Trig Values from an x-y coordinate Now we find the 6 trig functions just like we did before – set up the ratios with no square roots on the bottom y x

  5. Finding Trig Values from an x-y coordinate Now we find the 6 trig functions just like we did before – set up the ratios with no square roots on the bottom y x

  6. Finding Trig Values from an x-y coordinate Now we find the 6 trig functions just like we did before – set up the ratios with no square roots on the bottom y x

  7. Finding Trig Values from an x-y coordinate Find the 6 trig functions for an angle which has terminal side passing through (-3, -5) Remember that distances are positive so take the negatives off when you assign the distances to the proper sides y x Vertical – y, horizontal - x

  8. Finding Trig Values from an x-y coordinate Find the 6 trig functions for an angle which has terminal side passing through (-3, -5) y x

  9. Finding Trig Values from an x-y coordinate Find the 6 trig functions for an angle which has terminal side passing through (-3, -5) y x

  10. Finding Trig Values from an x-y coordinate Find the 6 trig functions for an angle which has terminal side passing through (-3, -5) y x
