Step-by-step explanation:
Let one of the numbers be x,
Then the two numbers are x and x +1
And,
x+x+1 = 53
2x = 53 - 1 (Transposing 1 from LHS to RHS)
2x = 52
x = 52/2
x = 26
x + 1 = 27
So, The two numbers are 26 and 27.

Answer:
y=t−1+ce
−t
where t=tanx.
Given, cos

x ....(1)
Here P=sec

xdx=tanx
∴I.F.=e
tanx
Multiplying (1) by I.F. we get
e
tanx

Integrating both sides, we get
