We are given the coordinates of a point, so: {eq}x_1 = 2 \\ y_1 = 1 {/eq} Now, substitute all the values into the point-slope formula: {eq}y - 1 =3(x - 2) {/eq} Simplify and solve for y:
The equation of a circle is x2 + y2 = r2. Based on this equation and the coordinates of the point, ( x, y ), where the terminal side of the angle intersects the circle, the six trig
