Two waves on one string are described by the wave functions $y_{1} = 3.0 \cos (4.0 x - 1.6 t) y_{2} = 4.0 \sin (50 x - 2.0 t)$ where x and y are in centimeters and t is in seconds. Find the superposition of the waves $y_{1} + y_{2}$ at the points (a) x = 1.00, t = 1.00; (b) x = 1.00, t = 0.500; and (c) x = 0.500, t = 0 Note: Remember that the arguments of the trigonometric functions are in radians.

The formula E = IZ, where E represents voltage, I represents current, and Z represents impedance (a measure of opposition to a sinusoidal electric current), is used in electrcal engineering. Each variable is a complex number. Use the formula to find the missing quantity for the given conditions. Then convert the given conditions to trigonometric form and check your result.

$I = 10 + 2 i, E = 4 + 5 i$
