If A + B = `45^(@)` , show that (1 + tan A)( 1 + tan B) = 2

If A+B=45^(@) , show that (1+tanA)(1+tan B)=2 .

If A +B = 45 ^(@), show that tan A + tan B + tan A tan B =1. Hence or otherwise, express tan 22 ^(@) 30' in surd form.

If A+B=45^(@) , then prove that (i) (1+ tan A) (1+ tan B) =2 (ii) (cot A-1) (cot B-1)=2

If angleA+angleB = 90^@ , show that 1+ (tan A)/(tan B) = sec^2A .

If angleA+angleB = 90^@ , show that 1+(tan A)/(tan B) = sec^2B tan^2A .

If A-B=(3pi)/(4) , that show that (1- tan A) (1+tan B)=2

If A+B=45^(@) , then (1+ tan A)(1+ tan B) =__________

If A+B=45^(@) , then (1+ tan A)(1+ tan B) =__________

If A + B = 45^(@) , then find the value of (1+tan A)(1+ tan B)
