Answer
a) sin(1.1) = .89121
b) cos(1.1) = .45360
Work Step by Step
a. Since sin(1.1) is not a value on the unit circle of trigonometric values, you will have to use the calculator for this. Plug in sin(1.1) into your calculator to get .89121.
b. Since cos(1.1) is not a value on the unit circle of trigonometric values, you will have to use the calculator for this. Plug in cos(1.1) into your calculator to get .453560.
