Okay, so given the point 6 square root of 3 and negative 6, what i could do first is figure out that this, draw this point.
00:09
So the x value is 6 square root of 3 and the y value is negative 6.
00:13
I can plot that point and create a right triangle, the cubed angles attached to the x -axis.
00:20
Now i already know some of the side lanes, right? the y -axis is negative 6, the x is 6 square root of 3.
00:27
Before i find my trig ratios, i need all three sides of my right triangle.
00:31
How do i find my third? well, i could do this using the pythagorean theorem.
00:37
If i know two sides in a right triangle, i could find the third.
00:41
The leg squared plus the other leg squared equals the hypotenuse squared.
00:46
Legs are attached to the 90 degree angle.
00:49
So 6 squared, i'm going to distribute this, is 36 square root squared, square root of 3 squared, those cancel, is times 3.
00:57
This will be plus negative 6 times negative 6 is positive 36 and this will be 108 plus 36 which is 144 when i combine those opposite a square to square root and my hypotenuse will be positive 12 hypotenuse is always across from the 90 degree angle now how do i find my trig ratios ratios.
01:23
Well, i can use an acronym here...
