Knowing cosx= 2 3 and the terminal point is in the fourth quadrant find sinx. ... Knowing cscx=-4 5 and the terminal point is in the third quadrant find cotx. Graphing – Class Work. ... A ship at sea noticed two lighthouses that according to the charts are 1 mile apart.
Activity overview:
Prove: (1 + cosx)(1 – cosx) = sin2x. (1 + cos(x))(1 – cos(x)) = 1 – cos2(x) = [sin2(x) + cos2(x)] – cos2(x) = sin2x. To verify this proof graphically, you will determine if the graph of the expression on the left side of the equation coincides with the graph of the expression …

a) Verify your results from #1 {b c e f} with a calculator. b) Verify your results from #1 {a d) without using a calculator. Write in terms of secant. Recall that cosecant is the reciprocal of the sine function and secant is the reciprocal of the cosine function. Express cscx using an equivalent trigonometric expression involving secant.
