Answer:
Step-by-step explanation:
In the first part, we are given the function:
Suppose we make x = tan θ
Then dx = sec² θ.dθ
Since; sec² θ - tan² θ = 1
sec² θ = 1+ tan² θ
∴
Thus; In the first part, Use x = tan θ, where , since the integrand comprise the expression
From the second part by using substitution method;
Ok
6+1=7
if only we could find 1
hmm
4+1=5
so mark a starting line
put the 4 inch and 5 inch wood at that line, facing the same direction (lying flat on paper)
the difference between the pieces of wood is 1 inch
mark the end of the 5 inch and the end of the 4 inch
that is 1 inch
now pick either end of that 1 inch mark and measure 6 inches more
