(1+tan^2 A)cot A/cosec^2 A= tanA

Rufina [12.5K]

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identities

1 + tan²A = sec²A , secA = $\frac{1}{cosA}$ , cosecA = $\frac{1}{sinA}$ , cotA = $\frac{cosA}{sinA}$ , tanA = $\frac{sinA}{cosA}$

Consider the left side

$\frac{(1+tan^2A)cotA}{cosec^2A}$

= $\frac{sec^2AcotA}{cosec^2A}$

= $\frac{\frac{1}{cos^2A}(\frac{cosA}{sinA}) }{cosec^2A}$

= $\frac{\frac{1}{cosAsinA} }{\frac{1}{sin^2A} }$

= $\frac{1}{cosAsinA}$ × sin²A

= $\frac{sinA}{cosA}$

= tanA = right side , thus proven

Complete Question

The complete question is shown on the first and second uploaded image

Answer:

$\= HK = \= t + \= u$

$\= GL = \= s - \= t$

$\= JH = \= u + \= s$

Step-by-step explanation:

Now looking at the diagram

Following the direction of the unit vectors $\= u , \= s, \= t$

$\= {HK} = \= {KI} + \= KL$

=> $\= HK = \= t + \= u$

And

$\= GL = \= GH + \= GF$ jjj

=> $\= GL = \= s - \= t$

Also

$\= JH = \= JG + \= JI$

=> $\= JH = \= u + \= s$
