2017年4月27日 · The velocity v m s –1 of a particle at time t seconds, is given by v = 2t + cos2t, for 0 ≤ t ≤ 2. (a) Write down the velocity of the particle when t = 0. When t = k, the acceleration is zero.

2014年11月15日 · For these kinds of problems, to avoid confusing squares and 2t's, you really need to put all the parenthesis in exactly where they are in the problem.

Help solve algebraically: sin2t cost - cos2t sint = 0 on the interval: (in description) problem in title but with interval being: 0 is less than or equal to theta which is less than or equal to 2 pi. Can someone also solve it using the Subtraction Identity

2022年10月13日 · Find an answer to your question if x = a sin 2t (1+cos2t) and y=b cos2t (1-cos2t) find the value of dy/dx at T = π/6 Weeeeeeex Weeeeeeex 14.10.2022

2019年12月6日 · cost=-7/8. therefore, sint=-√15/8 using the Pythagorean Theorem. now use the following trig identities and substitute the two values:
