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
∫tan(x)dx
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)
