7*xy^(2)-x^(2)y-5=0

Add the algebraic expressions: 4xy^(2)-7x^(2)y,12x^(2)y-6xy^(2),-3x^(2)y+5xy^(2)

Simplify the following : 3xy^(2) - 5x^(2)y + 7xy - 9xy^(2) - 4xy + 6x^(2)y

Solution of D.E (dy)/(dx)=(2x+5y)/(2y-5x+3) is,if (y(0)=0) (1) x^(2)-y^(2)+5xy-3y=0 (2) x^(2)+y^(2)+5xy-3y=0 (3) x^(2)-y^(2)+5xy+3y=0 (4) x^(2)-y^(2)-5xy-3y=0

If the acute alngles betwene the pairs of lines 3x^(2)+7xy+4y^(2)=0 and 6x^(2)-5xy+y^(2)=0 are theta_(1) and theta_(2) then

If theta_1 and theta_2 are the acute angle between the lines given by 3x^(2)-7xy+4y^(2)=0 and 6x^(2)-5xy+y^(2)=0 , then
