Mathematics: Post your doubts here!
We have to convert to R Cos...so a is going to be the coefficient of cos and b is the coefficient of sin Recall; R = Square root of a^2 + b ^2 α = tan inverse of ( b/a) R = ( 8^2 + 15^2 ) ^ (1/2) = 17 α = tan inverse of ( 15/8 ) = 61.9 ( 1 d.p) Now for second part 8 cos θ... -

log ( x^ 2 - x + 2 ) = 1 + 2 log x i am ignoring the base 2, since i cannot right subscript, hence i will make both the side have log such that we can ignore them on the following steps log ( x^ 2 - x + 2 ) = log 2 + log ( x ^ 2 ) Recall log a + log b = log ( ab ) log ( x^ 2 - x + 2 ) =... -

Rutzaba showed you the way. ( x / a ) + ( y / b ) = 1 Use the first information; to find P and Q. On x-axis, y=0 x = a. Hence Coordinate P ( a , 0 ) On y-axis, x = 0 y = b. Hence Coordinate Q ( 0, b) Next nformation; Length PQ is (45^ (1/2) ) manipulating the data; a^ 2 + b ^ 2... -

My friend, analyse well, put your hand on the line which is normal to the curve at C and go down from the value of x of point A and value of X for point C. You see the area H that i talked of is infact that area of trapezium that is mentioned in the marking scheme. -

We will have to solve by part. Consider Late, x is algebraic while e ^ ( 2*x) is exponential. Hence; u = x ; v = ( e ^ ( 2* x ) ) / 2 du/dx = 1 ; dv/dx = e ^ ( 2*x) integration of (xe^2x) dx = u * v - integration of v du = x * ( e ^... -
