Find the indefinite integral. (Remember to use absolute values where appropriate. Use C for the constant of integration.) 1 x 9x2 16 dx

Expression given :

We know,

So,

Therefore, indefinite integration of given expression is .

Hence, this is the required solution.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
