-k t-k k-x k-t x k--
A unit vector perpendicular to the plane determined by the vectors 4^i+3^j−^k and 2^i−6^j−3^k
The coefficient of expansion of a crystal in one direction (x-axis) is 2.0×10−6 K−1 and that in the other two perpendicular directions (y and z-axes) is 1.6×10−6 K−1,What is the coefficient of cubical expansion of the crystal?
Find the value of k, If x+k is a factor of the polynomials:
x^4-k^2x^2+3x-6k.
Check whether the two vectors, →A=−3ˆi−7ˆj+9ˆkand→B=−2ˆi−21ˆj+6ˆkare parallel to each other
