Find the value of sin75°. Trigonometry deals with the measurement of angles and helps us study the relationship between the sides and angles of a right-angled triangle. Answer: The value of sin75° is (√3 + 1)/ (2√2). Let's look into the steps to find the value of sin 75°. We can write sin 75° as, sin 75° = sin (45° +30° ) We know that,

Use our sin(x) calculator to find the exact value of sine of 75 degrees - sin(75 °) - or the sine of any angle in degrees and in radians.

2020年11月7日 · The exact value of sin(75°) is found using the sum of angles formula for sine, resulting in (sqrt(6) + sqrt(2))/4. Explanation: To find the exact value of sin(75°), we can use the sum of angles formula for sine, which states that sin(A + B) = sin(A)cos(B) + cos(A)sin(B) .

What is the value of sin (75) ?

2022年11月2日 · Answer: The value of sin 75 is (√3+1)/2√2. Let us find the value of sin 75 using the formula of the compound angles of sine functions. The following formula is the key to find sin 75 degree: sin (A+B) = sin A cos B + cos A sin B. Note that we can write sin 75 as follows: sin 75 = sin (45 + 30) = sin 45 ⋅ cos 30 + cos 45 ⋅ sin 30.

2019年5月23日 · As we know, sin (A + B) = sin A cosB + cos A sinB Hence, sin 75° = sin (45° + 30°) = sin 45 cos 30 + cos 45 sin30 ⇒ (1/√2)
