Dear student,


For terms of the form x2 + a2 or √x2 + a2, put x = a tanθ or a cotθ


 


          For terms of the form x2 - a2 or √x2 – a2 , put x = a sec θ or a cosecθ


 


          For terms of the form a2 - x2 or √x2 + a2, put x = a sin θ or a cosθ


 


•         If both √a+x, √a–x,  are present, then put x = a cos θ.


 


•         For the type √(x–a)(b–x), put x = a cos2θ + b sin2θ
