Sin 45 degrees exact value

to collect MCAT Math study guide cheat sheet for list of equations and values to memorize special angles to find exact values of expressions involving sine, cosine and tangent values of 0, 30, 45, 60 and 90 degrees, How to find sin, cos, tan, cot, csc, a) the exact expression; b) the most appropriate approximative formula. c) Explain why your chosen approximative formula gives the best value. φ1 = 45◦ φ2 = 135◦. HPBWφ = φ2 −φ1 = 90◦ = π.

-1/2. (a) Since 315 degrees is between 270 degrees and 360 degress, then sin 315 is evaluated in the 4th quadrant, and there is 45 degrees between the terminal Solution · Steps · $\mathrm{Use\:the\:following\:trivial\:identity}:\quad\sin\left(45^{\ circ\:}\right)=\frac{\sqrt{2}}{2}$ Use the following trivial identity : sin(45 ◦ )=√22.

sin(345) = sin(300 + 45).and using sin(A + B) = sinAcosB + sinBcosA, we have. 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 ) .
