#1 Posted 1:30pm 07-03-10 TOGHT INTEGRAL (2)IF ∫(sin 3θ + sin θ)e[p]sin θ[/p] cos θ dθ = (Asin [p]3[/p]θ + Bcos [p]2[/p]θ + Csin θ + D cos θ + E)e[p]sin θ[/p] + c find A, B , C , D , E ANS---> -4 , -12 , -20 , 0 , 32 respectively
In every loss, in every lie, in every truth that you'd deny
And each regret and each goodbye was a mistake too great to hide
And your voice was all I heard that I get what I deserve

#2 Posted 2:11pm 07-03-10 Re: TOGHT INTEGRAL (2)its really easy integral put sinθ=t question is now ∫((4t+4) +(12t[p]2[/p]+24t)-(24t +24) -(4t[p]3[/p]+12t[p]2[/p])+20 )e[p]t[/p].dt =e[p]t[/p](4t +12t[p]2[/p] -24t - 4t[p]3[/p] +20 ) done!
