LOL. A simple one would be enough. I know how to do it if it's X, just need Ymaths is fun, no?
you want a simple one or that special case?? coz i think u know how to work out for curves like y=x^2

Find area of the region bounded by y=x^2 , y-axis , y=1 and y=2.LOL. A simple one would be enough. I know how to do it if it's X, just need Y
you're welcomeThank you anonymous
thanks!ok, when you have a question in that form u need to change it to the form x+ yi and to do this u multiply the denominator by the conjugate (1-i) and u multiply the nominator by the conjugate so..
2/1+i = 2(1-i)/(1+i)(1-i) = 2-2i/(1^2 + 1^2) = 1-i
the mod of |1-i| = √(1^2 + 1^2) = √2
arg (z) = tan^-1 (-1/1)
u^2 = (1-i)(1-i) = -2i
that's all, hope u got it bro!
helppp2x-y-3z = 7 --------(1)
x+2y+2z = 0 -----------(2)
(1)*2 + (2): 5x-4z = 14 =====> x =1/5 ( 14 +4z) ---------(3)
Substitute (3) into (1):
2/5 ( 14 +4z) - y - 3z =7
28/5 +8/5 z - y -3z =7
y= -7/5 - 7/5z
Hence, vector equation of line is given by r = (x, y ,z)
= ( 14/5 + 4/5 z , -7/5 - 7/5z, z)
= (14/5, -7/5 , 0) + z ( 4/5, -7/5, 1)
= (14/5, -7/5 , 0) + z/5 ( 4, -7, 5)
= (14/5, -7/5 , 0) + λ ( 4, -7, 5) where the parameter λ = z/5 (shown)
Hope this helps. Peace.

ofc u have to show it...you have the option for integration in your calculator too but it doesn't mean u can just write the answer without showing the working..i was wondering whether you have to show the working to a quadratic equation's answer or if the values of "x" directly would suffice ?? (since it is a real headache, when you get the answer directly using the calc )
can someone please help me with 9(ia)

someone please help me with no 8
thanks in advance
thnx a lot!Note that for when k=2, cos^2 x will have a range given by [ 0, 1] for the domain [0, pi]
Hence, the range of f would be [ 3-4 =-1, 3-0=3] (shown)
Hope this helps. Peace.
