On a Cartesian graph I have a point at $x = 0$ and $y = 0$. This point needs to move forward at a $30^\circ$ angle. It should travel forward at this angle for $1.75$ on the graph. What equation can I use to do this?
Summary:
- Cartesian graph point $(0, 0)$
- Moves forward at a $30^\circ$ angle
- Needs to travel forward at the angle $1.75$ on the graph
- Is there an equation for this?
There is an way to determine the coordinates of the point. I assume that you mean "moves $1.75$ units along a line in the first quadrant that makes a $30$ degree angle with the positive x-axis", or something like that.
Draw a reference right triangle
This one is pretty sloppy... learn "SOHCAHTOA", a mnemonic device for trig ratios. Then we can say $$\cos(30) = x/1.75 $$
$$\sin(30) = y/1.75$$ And solve for x, y.
