    (tan9 + tan7) + (tan5+tan3) + 4(tan7+tan5) tan n + tan (n+2) = 1/(n+1) so for tan9 + tan7 it will be 1/(7+1) for tan3 + tan5 = 1/(3+1) for tan5 + tan7 = 1/(5+1) 1/(7+1) + 1/(3+1) + 4*1/(5+1)

    iib) (tan9 + tan7) + (tan5+tan3) + 4(tan7+tan5) we have the integration for tan(n) + tan(n+2). so we will open all these according to the formula. we wrote 4(tan7+tan5) cox there are 5tan7 and 5tan5. and only one of them are used with tan9 and tan3 respectively

    tangent passes through point P and through the origin. at point P the x coordinate is "p". at origin it is 0. the tangent will have same gradient at both the points. take out the gradient of P by diffrenciating the equation given. the gradient at origin will be (y-y1)/(x-x1) at origin x and y...

    u r asked to find the coordinates means the value of x and y. u found x=2. now keep it in the equation to find y. it will be ln2 +1 so coordinate is x,y 2, ln2+1

    0.095n + 1.65 = lnC 1.16n + 0.05 = lnC 0.095n + 1.65 = 1.16n + 0.05 1.65 - 0.05 = 1.16n - 0.095n 1.6 = 1.065n n = 1.5 0.095(1.5) + 1.65 = lnC lnC= 1.79 C = e^1.79 C = 6

    i) ln(x^ny) = lnC ln(x^n) + lny = lnC nlnx + lny = lnC nln1.10 + ln5.20 = lnc nln3.20 + ln1.05 = lnC solve them simultaneously. u will get the value of n and C

    omega is constant. it does not depend on radius. its a horizontal circle and for horizontal circles, omega is constant

    we will not use this formula for centripetal force cox v changes with the radius. we will use mrw^2 cox mass is constant and w is also constant for every point

    make a power time graph. calculate the avg power. equate it to (I^2 * R) or (V^2/R). this current or voltage will be rms. if the graph is rectified ac with linear change as it is in nov 2003 p4 q4, then (final+initial)/2
