Ncert solutions class 11 maths chapter 3 exercise 3.4 question 7. find the general solution for each of the following equations: sin 2x cos x = 0. summary: the general solutions of sin 2x cos x = 0 are x = [(2n 1)π 2] or [nπ ( 1) n 7π 6], where n∈z. There are two ways to solve the equation. your method: 2sinxcosx cosx = 0, so cosx(2sinx 1) = 0. thus we have either cosx = 0 or sinx = − 1 2. thus x = π 2 2nπ or x = − π 2 2nπ (from cosx = 0) x = − π 6 2nπ or x = 7π 6 2nπ (from sinx = − 1 2) (you grouped together the families of solutions of cosx and of sinx. A basic trigonometric equation has the form sin (x)=a, cos (x)=a, tan (x)=a, cot (x)=a. the formula to convert radians to degrees: degrees = radians * 180 π. the cotangent function (cot (x)), is the reciprocal of the tangent function.cot (x) = cos (x) sin (x) high school math solutions – trigonometry calculator, trig equations.
