Sir in time 0:55 you write ycos sin² how sir ycos cos² hona tha na
Sir last question me denominator negative nhi hota na
Yes in standard form we don’t keep - ve sign in denominator but if you keep - ve sign in denominator your marks will not get deducted thanks for your keen observation
Sorry for the mistake as we take cos fro cos ^3 so it will be y cos cos^2 in 2nd and 3rd step else process and solution is correct
