In mathematics, sin-30° represents the sine of an angle of -30 degrees. According to the properties of trigonometric functions, sin(-θ) = -sin(θ), so sin-30° equals -sin30°. We know that the value of sin30° is 1/2, so: sin-30° = -sin30° = -(1/2) = -0.5 所以,...

sin 30 degrees is equal to which of the following: a) cos 30 degrees b) sin 60 degrees c) tan 60 degrees d) cos 60 degrees Which is a value of x if sin 60 degrees = cos(x+10) degrees 1) 10 degrees 2) 20 degrees 3) 50 degrees 4) 60 degrees. Write sin 2...
Answer to: True or False: sin 60 degrees = cos 30 degrees = sqrt3 / 2 By signing up, you'll get thousands of step-by-step solutions to your...
Sin 90 degrees = 1 The angles are determined using the primary functions of sin, cos, and tan, while the secondary functions of cosecant, secant, and cot are obtained from the primary functions. 0°, 30°, 45°, 60°, 90°, 180°, 270°, and 360° are the most common degrees. ...
Hence, sine 120 degrees = sin 60 degree From thetrigonometry table, we can see that the value of sin 60 degree is equals to \[\frac{\sqrt{3}}{2}\] Hence, the value of sin 120 degrees is \[\frac{\sqrt{3}}{2}\]. Method 2 ...
time in school that π = 180°. So, if the angle is in degrees, multiply it by π/180° to convert it to radians. In Excel, this conversion can be written PI( )/180. For example, to convert 60° to radians, the Excel expression would be 60*PI( )/180, which equals 1.0472 ...
0.4226 (not rounded) all you do is type in your number then press sin if you are doing these calculations on the computer but if you are on a calculator then you would press sin and then the number. Just learned trig in my geometry class, its fun and easy. ...
Sin 18 degrees is the value of sine trigonometric function for an angle equal to 18 degrees. Understand methods to find the value of sin 18 degrees with examples and FAQs.
