As it is, there's only a few angles for which the sine and cosine functions have exact values - 30, 45, and 60 degrees are the useful ones, and it's also possible (once knowing these) to find others such as 15 degrees.

If we know one of the three trig values for an angle, we can find the other two by using these identities. Identities are useful for changing from one form to another when solving equations, and for finding exact values for trigonometric functions. A trolley of negilible mass on horizontal tracks is at rest. A person of mass 50kg is standing on the trolley with a bag of mass 10kg. The person throws the bag off the trolley horizontally with a velocity of 3m/s. Solved: Find the exact value: sin ( 22.5 ) .

Sin 45 degrees exact value

- Answered by a verified Tutor The trivial values. In degree format, sin and cos of 0, 30, 45, 60, and 90 can be calculated from their right angled triangles, using the Pythagorean theorem. In radian format, sin and cos of π / 2 n can be expressed in radical format by recursively applying the following: Learn the value of sin 60 degrees along with other degree values like 0, 30, 45, 90, 180, 270 and 360 (degrees). Also, know the values of cosine and tangent ratios. 2007-11-17 · How do you find the exact value of sin 15 degrees? Answer Save.

Homework Statement Find the exact value of sin 65o Homework Equations Trigonometry Identities The Attempt at a Solution I tried using sin 3x = 3 sin x - 4 sin3x but ended with nasty algebra. sin (3 . 65o) = 3 sin 65 - 4 sin3 65o sin (195o) = 3 sin 65 - 4 sin3 65o sin (180o+15o) = 3 sin 65 -

(1). sin (45 ∘) = 1 2 2015-02-03 By the first quadrant triangle rule, the Cosine ∆, of an angle is equal to the Sine (90°-∆), of its complement. Given ∆ = 50°, and Cos50° = 0.64, Then Cos50° = Sin (90°-50°) = Sin40° By the rule, Cos50° = Sin40° Find the exact value (no decimals) of sine of 105 degrees using the sum or difference formula.

Let’s find some exact values using some well-known triangles. Then we’ll use these exact values to answer the above challenges. sin 45°: You may recall that an isosceles right triangle with sides of 1 and with hypotenuse of square root of 2 will give you the sine of 45 degrees as half the square root of 2. There is a trick to remember the values of sine of angles 0,30,45,60 and 90. Write 0,1,2,3,4 below the above mentioned angle values , Divide each one by 4 0/4, 1/4, 2/4, 3/4, 4/4, Obtain square root of each of the above fractions, 0, 1/2 , 1/sqrt( First of all you need to assure that whether X(angle) is in degree or radian. After that you can find your result,Consider a right triangle with angle X= 45°,then it is obvious that third will also be 45°.hence the side length of trinagle are L, L Now let us discuss different values For sin For memorising sin 0°, sin 30°, sin 45°, sin 60° and sin 90° We should learn it like sin 0° = 0 sin 30° = 1/2 sin 45° = 1/√2 sin 60° = √3/2 sin 90° = 1 So, our pattern will be like 0, 1/2, 1/√2, √3/2, 1 As it is, there's only a few angles for which the sine and cosine functions have exact values - 30, 45, and 60 degrees are the useful ones, and it's also possible (once knowing these) to find others such as 15 degrees. Values of Trigonometric ratios for 0, 30,45, 60 and 90 degrees.
