Answer 1

Good Night!

lim Tan³x - 3Tan x

x->π/3 --------------------

Cos ( x + π/6 )

put x = π/3 We get 0/0 Now, we use L'HOSPITALS RULE.

lim 3 × Tan² x × Sec² x - 3 sec² x

x->π/3 ------------------------------------

- Sin ( x + π/6 )

Becoz Differentiation of Tan x is Sec² x

lim 3Sec² x { Tan² x - 1 }

x->π/3 ----------------------

- Sin ( x + π/6 )

Now, put x = π/3 we have

= 3 × ( 2 )² { (√3)² - 1 }

-----------------------

- Sin ( π/2 )

= -12 { 3 -1 }

= - 24

Answer 2

♣️ Welcome to the concept of limits ♣️

✨it is( 0/0) form

• you can solve it easily by l hospital's rule .
• or by evaluating cos (A+B)
• but l hospital's rule is easy in this question
• in applying l hospital's rule in question chain rule us also used ..

⏩yr answer is ( -24 )

⏩ i hope it help you ❤️

otherwise report it ..
