Will Medal First Answer


Can someone explain how inverse sine is used!

Answer 1

inverse sin gives you the angle given sin

Answer 2

i know that

Answer 3

Example: Solve for x in ΔPQR. Round the solution to the nearest hundredth degree.

[Image of a right triangle PQR is shown. Angle Q is the right angle. Angle P is x degrees. RQ equals 26. PR equals 47.]

sin ∠P = [Image of opposite over hypotenuse]

sin x° = [Image of 26 over 47]

Divide 26 by 47.

sin x° ≈ 0.5531914894

At this point, you will need to use the inverse sine to solve for x, which is the measure of angle P. You may do this by using the inverse sine button on your calculator, which looks like sin−1.

sin−1 (sin x°) ≈ sin−1 0.5531914894

Use your calculator to determine the value of sin−1 0.5531914894. Again, some calculators will require you to input sin−1, then 0.5531914894, and finally Enter. Others require you to input 0.5531914894 first and then sin−1. Refer to your calculator's manual or contact your instructor if you need assistance.

x ≈ 33.59°

Answer 4

Sin(30 degrees) = 0.5

Sin^-1(0.5) = 30 degrees

Answer 5

that is what i was trying to do, like how to input it into the calculator

Answer 6

2nd button sin?

Answer 7

or use wolframalpha

Answer 9

i used mathway

Answer 10

i think it gives the answer in radians

Answer 11

mathway is good, but it gives the answers in radians

Answer 12

The calc has two modes: degrees and radians

Answer 13

on mathway?

Answer 14

On a normal calculator

Answer 15

ik that, i am using online calculators

Answer 16

thanks
