Question

Give two values of between 0° and 180° for the given value of sin . Express your answers to the nearest degree. 0.9900

Answer 1

stick it in your calculator :), get the arcsin()

Answer 2

or \(sin^{-1}\)

Answer 3

i don't understand how to calculate it the right way though, i keep getting the wrong answer

Answer 4

make sure your calculator is in Degree mode :|

Answer 5

as opposed to Radian

Answer 6

1.4292568535 is the answer i keep getting .-.

Answer 7

right, that's the proper value for Radians

Answer 8

so you have your calculator in Radian mode, but the answer is required in Degrees

Answer 9

ooh, so if i just used a trig chart for radians to degrees i should get the answer right?

Answer 10

ahemm, calculators do both :|, if in Radian Mode, the trig functions give the Radian value, if in Degrees, they give the Degree value, yours is in Radian, but you need Degrees

Answer 11

so just change the Mode in the calculator to Degree

Answer 12

and redo the \(sin^{-1}\)

Answer 13

got it! it's 81.9, but that doesn't completely answer my question, it's asking for something in between two numbers

Answer 15

it's asking for something between, well, THERE :)
so 81.9 degrees is in the I Quadrant

Sine function is positive on the Quadrants Y is positive, so the other will be there

Answer 16

okay thanks :D
