How do you evaluate #arcsin(sqrt 3/2)#?
3 Answers
Explanation:
Because arcsin is a function
So
Make a right triangle with one side = sqrt 3 and the hypotenuse = 2 and use Pythagoras to find the other leg = 1
Explanation:
If you know that the sin 30 deg = 1/2 .............
Make a right triangle with one side = sqrt 3 and the hypotenuse = 2 and use Pythagoras to find the other leg = 1
That makes the sign of the complementary angle = 1/2 which implies the angle = 30 deg,
the angle in question = 90 - 30 = 60 degrees or
OR
Just calculate (sqrt 3) / 2 and find the arcsin with a calculator
Explanation:
Trig Table gives as solution:
The unit circle gives another x that has the same sin value (sqrt3/2)
