Write the expression as the sin or cosine of an angle.
sin pi/3 cos pi/7 - sin pi/7 cos pi/3

The tangent of an angle is not which of the following? a) ratiob) proportionc) fractiond) opposite over adjacent

How many solutions does the nonlinear system of equations graphed bellow have?

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
