Please solve no k and m. ​

Step-by-step explanation:

soln no. k

LHS: cosø√1+cot^2ø

= cosø×cosecø

= cosø× 1/sinø

= cosø/sinø

= cotø

=√cosec^2-1. [: cot^2ø=cosec^2ø-1

according to equation

sending the (^2) will be

root over in another Sid]

= RHS proved

for number m take the help of the pic

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
