Did you know?
Webb180° – 60° = 120°. Also, we know that the trigonometric identity sin (180°- a ) = sin a. Now, Sin ( 180°- 120°) = sin 120°. Therefore, sin 120°= sin 60°. From the trigonometry table, … Webbsin (180° - 120°) = sin 60° -sin (180° + 120°) = -sin 300° cos (90° - 120°) = cos (-30°) -cos (90° + 120°) = -cos 210° ☛ Also Check: sin 50 degrees sin 0 degrees sin 75 degrees sin 47 degrees sin 206 degrees sin 23 degrees Discover the wonders of Math! Explore Examples Using Sin 120 Degrees Example 1: Find the value of 2 × (sin 60° cos 60°).
WebbFor cos 120 degrees, the angle 120° lies between 90° and 180° (Second Quadrant ). Since cosine function is negative in the second quadrant, thus cos 120° value = - (1/2) or -0.5. Since the cosine function is a periodic function, we can represent cos 120° as, cos 120 degrees = cos (120° + n × 360°), n ∈ Z. ⇒ cos 120° = cos 480 ... WebbStep 1: Make a fraction with the decimal number as the numerator (top number) and a 1 as the denominator (bottom number). Step 2: Remove the decimal places by multiplication. First, count how many places are to the right of the decimal. Next, given that you have x decimal places, multiply numerator and denominator by 10 x .
