2025年1月18日 · To find the value of sin 150° - cos 180°: *Step 1: Find the value of sin 150°* Using the trigonometric identity sin (180° - x) = sin x, we can rewrite sin 150° as sin (180° - 30°) = sin 30°. We know that sin 30° = 1/2. *Step 2: Find the value of cos 180°* We know that cos 180° = -1. *Step 3: Subtract cos 180° from sin 150°*

Answer to Question Compute the exact value of sin(150° + 45°).

Question: 9. Find the principal 5th root of 50(cos 150° + i sin 150°). 10. What is the quotient when 4 + 8i is divided by i³?

2020年10月10日 · Sin 30 = sin 150 = ½. Both are equal because the reference angle for 150 is equal to 30 for the triangle formed in the unit circle. The reference angle is formed when the perpendicular is dropped from the unit circle to the x-axis, which forms a right triangle. Since, the angle 150 degrees lies on the IInd quadrant, therefore the value of sin ...

Without using a calculator, compute the sine and cosine of 150° by using the reference angle. What is the reference angle? degrees. In what quadrant is this angle? (answer 1, 2, 3, or 4) sin(150) cos(150) (Type sqrt(2) for 2 and sqrt(3) for 3.)

A voltage v(t) = (120 V) sin [(150 rad/s)] is produced by an ac generator. What is the rms voltage and frequency of the source? Question 2 options: 85 V and 150 Hz 60 V and 24 Hz 170 V and 48 Hz 60 V and 24 Hz 85 V and 24

Calculate sin(150)° Since our angle is greater than 90 and less than or equal to 180 degrees, it is located in Quadrant 2. In the second quadrant, the values for sin are positive only. 150 is an obtuse angle since it is greater than 90° sin(150)=1/2

10.18 A machine is subjected to the vibration x (t) = 20 sin 50 t + 5 sin 150 t mm (t in s) An accelerometer having a damped natural frequency of 80 rad / s and an undamped natural frequency of 100 rad / s is mounted on the machine to read the acceleration directly in mm / s 2. Discuss the accuracy of the recorded acceleration.
