A particle starts from rest and moves in a straight line on a smooth
horizontal surface. Its acceleration at time t seconds is given by
k(4v + 1) ms^(−2)
where k is a positve constant and v ms^(−1) is the speed of the particle.
Given that v = ((e^2 −1)/4) when t = 1. show that
v = (1/4)(e^(2t) −1)
this trig integral has quite a few
insights on trig integrals andd
u subs as well as on the properties
of logarithms. try it out it′s a nice
one

hi every one
what is the scientific reason for using
trigonometric compensation
in integration?
and what is the rule that we rely on
in other compensation?
(√(a^2 −x^2 ))→→x=a sin(θ) OR a cos(θ)
(√(a^2 +x^2 ))→→x=a tan(θ) OR a cot(θ)
(√(x^2 −a^2 ))→→x=a sec(θ) or a csc(θ)
