3+2 cos theta
3+2 cos theta-Cos θ = – (√ 3/2) and π < θ < 3π Formula Used sin 2 θ cos 2 θ = 1 We need to use the following sign convention for the various trigonometric functions Calculation sinθ = ± √(1 – cos 2 θ) ⇒ √1 – (√3/2) 2} = √(4 – 3)/4 = ± (1/2) Here θ lies in the third quadrant, value of sinθ is negative So, sinθ = (1/2) Sinθ = 1/cosecθ ⇒ cosecθ = – 2 tanθĐặt điện áp u = U 0 cos(100πt π/3)(V) vào hai đầu một cuộn cảm thuần có độ tự cảm L = 1/2π H Ở thời điểm điện áp giữa hai đầu cuộn ảm là 100√2V thì cường độ dòng điện qua cuộn cảm là 2A Biểu thức của cường độ dòng điện qua cuộn cảm này là

Degrees to radians conversion; Write the value of the expression tan ((sin^1 x cos^1 x)/2), when x = √3/2 asked in Trigonometry by Takshii ( 351k points) inverse trigonometric functionsSolution Inverse trigonometric functionsare the inverse ratio of the basic trigonometric ratios Here the basic trigonometric function of Sin θ = y can be changed to θ = sin1 y Let, cos1(√3/2) = y Hence, cos y = (√3/2) = cos (π / 6) The range of the principal value of cos1(x) is (0, π) Thus, the principal value of cos1(√3/2) = π / 6
