Compute sin θ, cos θ and tan θ, for (a) θ = 1 (b) θ = 135 (c) θ = 210 (d) θ = −60 (minus 60 degrees) 2 What is the amplitude, the period and the phase of (a) 2 sin(x − π 2 ) (b) 2 cos(x) (c) 3 sin(2(x − π 4 )) 3 Compute (a) sin−1 (1/2) (b) sin−1 ( √ 2/2) (c) sin−1 ( √ 3/2) (d) cos(sin−1 (1/2)) (e) cosCos 30° = √3/2 is an irrational number and equals to (decimal form) Therefore, the exact value of cos 30 degrees is written as approx √3/2 is the value of Cos 30° which is a trigonometric ratio or trigonometric function of a particular angle Cos 30 Another alternative form of Cos 30° is pi/6 or π/6 or Cos 33 (⅓) gView HW6_solution_21pdf from MECH_ENG 3150 at Northwestern University HW6 Solutions 1 (70 pts) 11 (8 pts) (4 pts) The geometric continuity equation is ω = v3 /l3 = v4 /l4 ⇒ v3 = v4 /3 (4
Calculate cos(23)° Determine quadrant Since our angle is between 0 and 90 degrees, it is located in Quadrant I In the first quadrant, the values for sin, cos and tan are positiveValue of cos 30 Cos 30 degree value is √3/2 The term "trigonometry" deals with the study of the measurements of rightangled triangles with parameters such as length, height and angles of the triangle The important trigonometric angles are 0, 30, 45, 60, 90, 180, 270 and 360 The angles for six trigonometric functions like sine, cosineUnit Circle The circle of radius one centered at the origin in the xyplane 0º 0 (1,0) 30º π/6 (√3/2, 1/2) 45º π/4 (√2/2, √2/2) 60º
Find the principal value cos1 ((√3/2)) (A) (5π/6) (B) (π/6) (4π/9) (D) (2π/3) Check Answer and Solution for above question from MathematiPythagoras Pythagoras' Theorem says that for a right angled triangle, the square of the long side equals the sum of the squares of the other two sides x 2 y 2 = 1 2 But 1 2 is just 1, so x 2 y 2 = 1 (the equation of the unit circle) Also, since x=cos and y=sin, we get (cos(θ)) 2 (sin(θ)) 2 = 1 a useful "identity" Important Angles 30°, 45° and 60° You should try to rememberSOLUTION cos(AB) = 1 cos(AB) = cos0⁰ (AB) = 0 Now, cosB = √3/2 cos B = cos 30⁰ B = 30⁰ Now, AB =0 A 30 = 0 A = 30 Hence, (AB) = 3030 = 60 or π/3 ANSWER
