TheRD Sharma Solutions Class 10 is the most accurate resource for students to clarify doubts and prepare confidently for their exams. For detailed step-by-step solutions to exercise questions, students can download the RD Sharma Solutions for Class 10 Maths Chapter 6 Trigonometric Identities Exercise 6.1 PDF below. Evaluatecos((2pi)/3) Step 1. Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosine is negative in the second quadrant. Step 2. The exact value of is . Step 3. The result can be shown in multiple forms. cosx) cos ( x) Because the two sides have been shown to be equivalent, the equation is an identity. sin(x)cot(x) = cos(x) sin ( x) cot ( x) = cos ( x) is an identity. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. Sincethe terms in the inequality are divided by 2, we can multiply them by 2 to eliminate the denominator, simplifying the inequality. 1 ≥ sin(x)/x ≥ cos(x) Hang on, hang on. We are simplify:\frac{\sin^4(x)-\cos^4(x)}{\sin^2(x)-\cos^2(x)} simplify\:\frac{\sec(x)\sin^2(x)}{1+\sec(x)} simplify\:\sin^2(x)-\cos^2(x)\sin^2(x) simplify\:\tan^4(x)+2\tan^2(x)+1; simplify\:\tan^2(x)\cos^2(x)+\cot^2(x)\sin^2(x) Show More WhatAre Sin Cos Formulas? If (x,y) is a point on the unit circle, and if a ray from the origin (0, 0) to (x, y) makes an angle θ from the positive axis, Then, divide by 2 and isolate the product of cosines: cosα cosβ = (1/2)[cos(α−β) + cos(α+β)] Solveover the Interval sin(2x)=sin(x) , (0,2pi), Step 1. Subtract from both sides of the equation. Step 2. Apply the sine double-angle identity. Divide each term in by and simplify. Tap for more steps Step . Divide each term in by . The cosine function is positive in the first and fourth quadrants. Letf(x)= xsinx+cosxsinx−xcosx which is of the form vuf(x)= v 2uv−vu= (xsinx+cosx) 2(xsinx+cosx) dxd (sinx−xcosx)−(sinx−xcosx) dxd (xsinx+cosx)= (xsinx+cosx) 2(xsinx+cosx)(cosx−cosx+xsinx)−(sinx−xcosx)(xcosx+sinx−sinx)= (xsinx+cosx) 2(xsinx+cosx)(xsinx)−(sinx−xcosx)(xcosx)= (xsinx+cosx) 2x 2sin 2x+xsinxcosx−xsinxcosx+x cos^{2}(x)-\sin^{2}(x) en.
