[" (v) If "A+B=(pi)/(4)," then prove that "(cot A-1)],[qquad (cot B-1)=2]

If A+B=(pi)/(4), prove that: (1+tan A)(1+tan B)=2(cot A-1)(cot B-1)=2

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

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

If A+B=45^(circ) , prove that (cot A-1)(cot B-1) = 2

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

If A + B = (pi)/(4) , show that (cot A - 1) (cot B - 1) = 2 and hence deduce that cot 22^((1^(0))/(2))=sqrt(2)+1.

If A+B=225^(@) than prove that (cot A)/(1+cotA). (cot B)/(1+cotB)=(1)/(2)

Prove that cot^(-1) 7 + 2 cot^(-1)3 = pi/4

If A=60^(@) and B=30^(@) then prove that: cot(A-B)=(cot A cot B+1)/(cot B-cot A)

Prove that cot((pi)/(4)-2cot^(-1)3)=7
