It is: sin(90) = 1
x = sin-1 (4/15) ( sin -1 is [SHIFT] [sin] on a calculator ) = 15.5
The value of tan and sin is positive so you must search quadrant that tan and sin value is positive. The only quadrant fill that qualification is Quadrant 1.
what is the value of sin 75 degree
sin(49) = - 0.9537526528 ------------------------------In radian mode. sin(49) = 0.7547095802 -----------------------------In degree mode.
sin(49) = - 0.9537526528 ------------------------------In radian mode. sin(49) = 0.7547095802 -----------------------------In degree mode.
-- The sin of 1 degree is 0.01745. (rounded) -- The sin of 1 radian is 0.84147. (rounded) -- The sin of 1 grad is 0.01571. (rounded)
Sin(62 deg) = 0.8829Sin(62 deg) = 0.8829Sin(62 deg) = 0.8829Sin(62 deg) = 0.8829
In degrees they are the same value.
Sin -30
sin(37) = 0.6018150232
you have to do the arcsin which is sin-1 on your calculator. i have not met anyone in my life who can do sin or arcsin in their head. not even my college teachers. your theta is equal to 20degrees
12.5/sin(30) = 25 meters
The exact value of sin 22.5 is 0.382683432
22.20366435 sin^-1(0.3779)
