Question

The value of tan(-225°) cot
(-405°) - tan(-765°) cot (675) is
a. 1
b. 4
c. 2
d. 0
Plz give the correct answer ​

Answer 1

Answer:

0 Option D

Step-by-step explanation:

Tan(-225) = - tan (180 + 45)

         = - tan 45 = -1

cot (-405) = - cot ( 360 + 45)

                 = -1

Tan (-765) = - tan (360*2 + 45)

                = - 1

cot (675) = cot (360*2 - 45)

                = -1

Now,

(-1) x (-1) - (-1)(-1)

1 - (1)

1 - 1

= 0
