sin^2(x) = (1 - cos(2x))/2 and cos^2(x) = (1 + cos(2x))/2so sin^4(x) = 0.25(1 - 2cos(2x) + cos^2(2x)) = 0.25(1 - 2cos(2x) + 0.5 + 0.5cos(4x))integrate = 3x/8 - sin(2x)/4 + sin(4x)/32

Add silver nitrate to the aqueous solution. If a precipitate forms then solution contains halide ions. Chloride: white. Bromide: cream. Iodide: pale yellow. Adding dilute ammonia will dissolve the chlori...

Increasing the temperature of a reaction means increasing the kinetic energy of each particle in the reaction. Increasing a particle's kinetic energy means the particle is moving faster ('Kinetic' indicat...

A deletion in a strand of DNA would result in a frameshift mutation, where the other base pairs following the deletion would move 'to the left' which would change the base pairs throughout the rest of the...

Find the lowest common multiple of 2 and 3, which is 6. Multiply each term in the first equation by 3, and each term in the second equation by 2 to produce two equations with the same coefficient of x (wh...
