Each new topic we learn has symbols and problems …I ended up realizing that the easiest way to go about it would be to convert the $ cos^2(2\pi t) $ into a term without a square via the double angle formulas, so that it would turn into $ 1 \over 2 $ * $ cos(4\pi t) $ and some constant. Using the angular frequency formula above, the period then is 0.5s.Popular Problems Calculus Evaluate 2cos (pi/2) 2cos ( π 2) 2 cos ( π 2) The exact value of cos(π 2) cos ( π 2) is 0 0. 2⋅0 2 ⋅ 0 Multiply 2 2 by 0 0. 0 0 Free math problem solver …The value of cos pi/2 is 0. What is the Value of Cos pi/2 in Terms of Tan pi/2? We know, using trig identities, we can write cos pi/2 as 1/√(1 + tan²(pi/2)). How to Find Cos pi/2 in Terms of Other Trigonometric Functions?

Ex 3.3, 4 Prove that 2sin2 3π/4 + 2cos2 π/4 + 2sec2 π/3 = 10 Solving L.H.S 2sin2 3π/4 + 2cos2 π/4 + 2sec2 π/3 Putting π = 180° 2 sin2 (3 × 180/4 ) + 2cos2 (180/4) + 2sec2 (180/3) = 2sin2 (135°) + 2 cos2 (45°) + 2sec2(60°) Here, cos 45° = 1/√2 sec 60° = 1/cos⁡〖60°〗 = 1/(1/2) = 2 sin 135° = sin ( 180 – 45° ) = sin 45° = 1/√2 Putting values 2 sin2 (135 ... The average value of function f f over the interval [a,b] [ a, b] is defined as A(x) = 1 b− a ∫ b a f (x)dx A ( x) = 1 b - a ∫ a b f ( x) d x. Substitute the actual values into the formula for the average value of a function. The integral of cos(x) cos ( x) with respect to x x is sin(x) sin ( x). Simplify the answer.Oct 11, 2018 ...
