WebMar 28, 2016 · Explanation: Step 1: Add 1 to both sides: 2cos2(2x) = 1 Step 2: Divide both sides by 2: cos2(2x) = 1 2 Step 3: Take the square root of both sides: cos(2x) = √2 2 or cos(2x) = −√2 2 (don't forget the positive and negative solutions!) Step 4: Use inverse of cosine to find the angles: 2x = cos−1( √2 2) or 2x = cos−1( − √2 2) WebThe number of xepsilon [0, 2pi] for which √ (2sin^4x + 18cos^2x) - √ (2cos^4x + 18sin^2x) = 1 is: Class 11. >> Maths. >> Trigonometric Functions. >> Trigonometric Equations. >> The number of xepsilon [0, 2pi] for whic.

Consider h ( x) = cos ( x) − x. Then, h ( 0) = 1 and h ( π 2) = − π 2. Hence, h ( 0) > h ( π 2) and, clearly, h ( x) is continuous. For the IVT, there exist a z ∈ ( 0, π 2) such that h ( z) = 0. You could also use h ( 1) = cos ( 1) − 1 < 1 − 1 = 0 to get the argument working on the smaller interval.
Webx = 0 is a root of f ( x) already. Since f ( x) is an odd function, it suffices to find only positive roots, because if r < 0 is a root, then f ( − r) = − f ( r) = 0 as well and − r > 0. Now if a positive root existed, let's say r > 0, then according to Rolle's theorem, f ′ … WebHence, the number of values of x in [ 0, 2 π] is 4. Hence, option (D) is the correct answer.
