- Show that tan(45^(@) + A) = (1 + tan A)/(1 - tan A)
Text Solution
|
- (1 + tan ^ (2) (45-A)) / (1-tan ^ (2) (45-A)) = cos ec2A
Text Solution
|
- (1 + tan ^ (2) (45 ^ (@) - A)) / (1-tan ^ (2) (45 ^ (@) - A)) = csc2A
Text Solution
|
- tan(45^(@)+A)tan(45^(@)-A)=1
Text Solution
|
- If A+B=45^(@), then (1+ tan A)(1+ tan B)=
Text Solution
|
- (1-tan^(2)(45^(@)-A))/(1+tan^(2)(45^(@)-A)) is equal to
Text Solution
|
- (1- tan^(2) (45^(@)-A))/(1+tan^(2)(45^(@)=A)) =sin 2A
