Find the Exact Value arcsin(sin((3pi)/4)) | Mathway

Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. For math, science, nutrition, historySo, since sin (3pi/4) is the same as sin(pi/4). To find sin(pi/4) consider a right angled isosceles triangle with both arms a length of 1. The hypotenuse is simply the result of the pythagorean theorem 1 + 1 = c^2, c = sqrt(2). Since we have an isosceles triangle, we know that one angle must be pi/2 (or 90 degrees) and the other two angles mustFree Taylor Series calculator - Find the Taylor series representation of functions step-by-stepThe exact value of cos 3pi/4 is -1/√2. In a right triangle, the cosine angle is divide the length of hypotenuse (H) by the length of the adjacent side (A). The word sine comes from the Latin word sinus and the prefix 'co' with sine make the cosine word. Secondly, what is the exact value of sin 5pi 6? The exact value of sin(π6) sin ( π 6) is

Enter perspective in levels or radians:

Calculate 3 sin(3π/4)

Determine quadrant:

Since our angle is bigger than π/2 and not more than or equivalent to π radians, it is situated in Quadrant IIIn the second quadrant, the values for sin are certain best.

Determine attitude sort:

a hundred thirty five is an obtuse attitude since it's greater than 90°

sin(3π/4) = √2/2

Multiply our solution by our coefficient of 3

3sin(3π/4) = 3(√2/2)

In Microsoft Excel or Google Sheets, you write this serve as as =3*SIN(3PI()/4)
