**How do you find sin(pi/12) and cos(pi/12)? Socratic**

Use the SINE Function to calculate the sine of an angle. Simply enter the angle directly into the function or reference a cell containing the angle. Simply enter the angle directly into the function or reference a cell containing the angle.... 1. Introduction In this session we are going to be looking at the deﬁnitions of sine, cosine and tangent for any size of angle. Let’s ﬁrst of all recall sine, cosine and tangent for angles in …

**It Is Surprising But True Trigonometric Ratios Of Sine**

The trigonometric function cosine, like the sine and the tangent, is based on a right-angled triangle (a triangle containing an angle equal to 90 degrees) as shown in the image above. In math class, the cosine of an angle is found by dividing the length of the side adjacent to the angle by the... #x = cos(pi/12)# and #y = sin(pi/12)# Both are positive (since an angle #pi/12# is in the first quadrant). Also #x>y# since, as angle #phi# increases from 0 to #pi/12# , #cos(phi)# decreases from #1# and #sin(phi# ) increases from #0# .

- The SIN function returns the sine of an angle provided in radians. Sample Usage. SIN(PI()) SIN(1) SIN(A2) Syntax. SIN(angle) angle - The angle to find the sine of, in radians.
- The SIN function returns the sine of an angle provided in radians. Sample Usage. SIN(PI()) SIN(1) SIN(A2) Syntax. SIN(angle) angle - The angle to find the sine of, in radians.
- Multiplying both sides times 40, you're going to get, let's see. 40 divided by 30 is 4/3. 4/3 sine of 40 degrees is equal to sine of theta, is equal to sine of theta. Now to solve for theta, we just need to take the inverse sine of both sides. So inverse sine of 4 over 3 sine of 40 degrees. Put some parentheses here, is equal to theta. That will give us that angle here and we can use that
