If x = 0, then tan-Ir is

If x<0 then tan-1(1x) equals. check-circle. Answer. Step by step solution by experts to help you in doubt clearance & scoring excellent

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
