    Mathematics: Post your doubts here!

    ohh there is a derivation for the square root. But it's not necessary all you need to remember is removing modulus sign in complex number means square root of (real number ^2 + coefficient of imaginary number ^2) don't include i. You made that mistake don't include i after you square root it! (...

    Sorry about the x=y . |z-3|=|z-3i| now removing modulus sign we get sq rt of ((real component)^2+(imaginary component)^2) on both sides suppose z as x+yi you get sq rt of ((x-3^2)+y^2)=(x^2+(y-3)^2) remove sq rt by squaring both sides now solve to get x=y yeah vector parallel to x axis is...

    Sure! Midpoint of PQ is (p+q)/2 and get the position vector plane passes through this point now (q-p) gives direction of pq vector this is perpendicular to the plane so this direction can be considered as normal of the plane. Now you can substitue a,b,c as the normal direction you obtained. and...

    Thanks! but mark scheme says P as well and thanks for the general examples really helpful. But incase of only *element oxides* in the given periodic table in question is there some kind of general trend on the reducing strength of the *element oxides*?

    Can anyone help me with this 3 (ii)? And can you tell me how reducing power or oxidising power is affected (increases or decreases) in oxides of these elements. (general trend?) answer is : S or C or N or P

    du/dx =4cos4x and for integration of cos^3 4x write as cos4x * cos^2 4x dx I am ignoring the integration sign now onwards. =(4cos4x)/4 * (1-sin^2 4x) dx =du/dx (1-sin^2 4x)/4 dx (the dx is cancelled here) so (1-u^2)/4 du (since sin4x = u) Now the new limits for integration are found using...

    latent heat of vaporisation means heat needed to change into gas and latent heat of fusion to change into liquid, in liquid all the molecules are not free of each other that is they still have molecular interactions i.e. all the atoms are not free only some are free so less energy is required...
