Question

tan(45+ theeta). tan (45° - theeta)

​

Answer 1

Answer:

1- tan^2 theeta

Step-by-step explanation:

tan(45 + theeta) x tan (45 - theeta) is in the form:

= (x+y) (x-y)

= x^2 - y^2

similarly, the equation can be written as:

= (tan^2 45°) - (tan^2 theeta)

= (1)^2 - (tan^2 theeta)

= 1- tan^2 theeta
