The solution is found by applying the definition of complementary trig functions: Cos (&Theta) = sin (90°-&Theta) cos (62°) = sin (90°-62°) Therefore the solution is sin 28°.
For angles greater than 360 degrees, subtract multiples of 360 so that the relevant angle (the remainder) is between 0 and 360 degrees. Then For 90 < x ≤ 180 deg, sin(x) = sin(180-x) For 180 < x ≤ 270 deg, sin(x) = -sin(x-180) For 270 < x ≤ 360 deg, sin(x) = -sin(360-x)
The exact value of sin 22.5 is 0.382683432
0.33
sin(x) = 0.4 x = 23.578 degrees (rounded) x = 0.4115 radian (rounded) x = 26.198 grads (rounded)
It is: sin(90) = 1
sin 90 is 1
sin(90) = 1
The solution is found by applying the definition of complementary trig functions: Cos (&Theta) = sin (90°-&Theta) cos (62°) = sin (90°-62°) Therefore the solution is sin 28°.
Assuming you mean -90 degrees, not radians: tan (-90) = [sin(-90)]/[cos(-90)] = (-1) / 0 You cannot divide by zero. tan (-90) is undefined/does not exist.
The value of sin A is 5.82 and the actual angle is 19.47 degees
sin(30) = sin(90 - 60) = sin(90)*cos(60) - cos(90)*sin(60) = 1*cos(60) - 0*sin(60) = cos(60).
sin θ = cos (90° - θ) cos θ = sin (90° - θ)
sin(90 deg) = 0.9848, approx.
