t+ah=11

Write t_(2) and t_(3) for the A.P., if (i) a=11,d=2 (ii) a= -7, d= - 5

Which of the following molecules is not ah exception to octet rule?

State whether true (T) or false (F): 17 - 11 = 11 - 17

The number of real solutions (x,y,z,t) of simultaneous equations 2y=(11)/(x)+x2z=(11)/(y)+y,2t=(11)/(z)+z,2x=(11)/(t)+t is

The number of real solutions (x, y, z, t) of simultaneous equations 2y=11/x+x , , 2z=11/y+y , 2t=11/z+z , 2x=11/t+t is

If x=e^t sin t , y=e^t cos t , t is a parameter , then (d^2y)/(dx^2) at (1,1) is equal to

If x=e^t sin t , y=e^t cos t , t is a parameter , then (d^2y)/(dx^2) at (1,1) is equal to

Subtract : 3t ^(4) - 4t ^(3) + 2t ^(2) - 6t + 6 from - 4t ^(4) + 8t ^(3) - 4t ^(2) - 2t + 11
