ఇచ్చింది:

A = 60° మరియు B = 30°

ఉపయోగించిన సూత్రం:

Tan 60° = √3

Tan 30° = 1/√3

గణన:

 (tan 60° - tan 30°)/(1 + tan 60° × tan 30°)

⇒ {√3 - (1/√3)}/{1 + (√3 x 1/√3)}

⇒ {(3 - 1)/√3)}/{1 + 1}

⇒ 2/√3/2 =

∴ సరైన సమాధానం .

Shortcut Trick గణన:

= t an (A - B)

= tan (60 - 30)

= tan 30°

=

∴ సరైన సమాధానం .
