since d/dx[c]=0

∫0dx=C

since d/dx[Kx]=K

∫Kdx=Kx+C

since d/dx[Kf(x)]=Kf’(x)

∫Kf(x)=K∫f(x)dx=Kf(x)+C

since d/dx[f(x)±g(x)]= f’(x)±g’(x)

∫f’(x)±g’(x)dx=f(x)±g(x)+C

since d/dx[x^n]=nx^n-1

∫x^ndx= (x^n+1)/x+1 + C

since d/dx[sinx]= cosx

∫cosxdx=sinx + C

since d/dx[cosx]= -sinx

∫sinxdx= -cosx + C

since d/dx[tanx]=sec²x

∫sec²xdx= tanx + C

since d/dx[secx]=secxtanx

∫secxtanxdx = secx + C

since d/dx[cscx]= -cscxcotx

∫cscxcotx dx = -cscx + C

since d/dx[cotx] = -csc²x

∫csc²xdx = -cotx + C
