How do you calculate the angle if you know Sin of the angle?
type the value of sine in the calculator and press 2ND SIN for sin-1, or press 2ND SIN for sin-1 and type the value of sine, because -sin(.xxxx) = angle known as inverse sine
What is the formula for calculate 3 phase power MVAR?
Q = 3 Vph Iph sin(phase angle) = 31/2 Vline Iline sin(phase angle)
How do you calculate trigonometric ratios of obtuse angles?
If ø is an obtuse angle then (180 - ø) is an acute angle and: sin ø = sin (180 - ø) cos ø = -cos (180 - ø) tan ø = -tan (180 - ø)
How do you calculate the ideal mechanical advantage of an inclined plane?
Its the reciprocal of the sine of the ramp angle. > 1 / ( sin ( ramp angle ) )
How do you find measure of each angle in triangle?
Important Formula: Sin(q) = Opposite / Hypotenuse Cos(q) = Adjacent / Hypotenuse Tan(q) = Opposite / AdjacentSelect what (angle / sides) you want to calculate, then enter the values in the respective rows and click calculate. If you want to calculate hypotenuse enter the values for other sides and angle.
In triangle abc given that angle a equals 57 angle b equals 73 and ab equals 24cm find the length of ac?
The sum of the angles inside a triangle is equal to 180°. We are told that angle a is 57°, and that angle b is 73°. This tells us that angle c is is (180 - 57 - 73)°, or 50°. We are also given the length of side ab, 25cm. With that, we can use the sine rule to calculate the length of side ac: sin(b) / |ac| = sin(c) / |ab| ∴ sin(73°) / |ac| = sin(50°) / 24cm ∴ |ac| = 24cm · sin(73°) / sin(50°) ∴ |ac| ≈ 29.96cm
What is the difference between sin x and sin -1 x .?
-- sin(x) is a number. It's the sine of the angle 'x'. -- sin-1(x) is an angle. It's the angle whose sine is the number 'x'.
How do you calculate power angle of a synchronous generator?
tan (phi)= (V* sin (theta) + Ia*Xs)/(V*cos (theta) +Ia*ra) theta is power factor angle torque angle= phi-theta
If the sin 0.58333 what is the angel?
You can calculate that on any scientific calculator. Make sure you put it into the correct angle mode (degrees, or radians, depending on what you need), and press something like "inverse", followed by "sin".In Excel, you can type: =asin(0.58333) That will give you the angle in radians.
What is the formula to caluclate angle of refraction?
The formula to calculate the angle of refraction is given by Snell's Law: n₁sin(θ₁) = n₂sin(θ₂), where n₁ and n₂ are the refractive indices of the initial and final medium, and θ₁ and θ₂ are the angles of incidence and refraction, respectively.
When the angle of refraction is 20 degrees what is the angle of incidence?
To find the angle of incidence when the angle of refraction is 20 degrees, you can use the formula for Snell's Law: n1 sin(θ1) = n2 sin(θ2). Given that n1 and n2 are the refractive indices of the media and we know θ2 (20 degrees), you can calculate θ1.
What is sin theta minus 1?
That expression can't be simplified. If you know how much the angle (theta) is, you can calculate the sine (do it on a calculator), and then subtract 1.
