Step 2 the exact value of is. Web algebra evaluate sin((5pi)/4) step 1 apply the reference angleby finding the anglewith equivalenttrig values in the first quadrant.

By repeated application of angle sum formulas we may get, sin(5x)= sin5x+ 5cos4xsinx− 10sin3xcos2x let x = 5π and let sin(5π) = u then we have, 0 = u5 + 5(1−u2)2u− 10(1− u2)u3. Make the expression negative because sine is negative in the fourth quadrant. Extended keyboard examples upload random. The value of sin pi/4 is 1/√2 or 0.7071 (approx). If you don't know the trigonometric circle, you can see that if one of the small angles of a rectangle triangle is π 4, the other will be also π 4, which implies the catets are equal. It was found using extremely difficult and time consuming math that is too much trouble to explain. and then maybe point towards a resource to check it out. Web algebra evaluate sin((3pi)/4) step 1 apply the reference angleby finding the anglewith equivalenttrig values in the first quadrant.

By repeated application of angle sum formulas we may get, sin(5x)= sin5x+ 5cos4xsinx− 10sin3xcos2x let x = 5π and let sin(5π) = u then we have, 0 = u5 + 5(1−u2)2u− 10(1− u2)u3. By the pythogoras theorem we know that x2 + y2 = 1. If you don't know the trigonometric circle, you can see that if one of the small angles of a rectangle triangle is π 4, the other will be also π 4, which implies the catets are equal. Web sin( 7π 4) sin ( 7 π 4) apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Step 3 the result can be shown in multipleforms. √2 2 the result can be shown in multiple forms. It was found using extremely difficult and time consuming math that is too much trouble to explain. and then maybe point towards a resource to check it out. So if x=y, you will have x2 +y2 = 1 Web in the trigonometric circle π 4 is the bisectrix between 0 and π 2, where x=y. Web sin pi/4 is the value of sine trigonometric function for an angle equal to pi/4 radians.
