A: Here I am attaching image so that you understand each and every step.

A: We can solve given problem by using G.P series.

A: We need to find lower and upper estimate.

A:

A: We know that tan θ=Opposite sideAdjacent sidetan(68)=x21

A: b) We check if the denominator is 0 for any value of x.  2x2+5=0 2x2=-5 x2=-5/2 (not possible) So…

A: It's trigonometric question so I'm providing hand written solution for better understanding.

A:

A: Given: simplify the expression
