Question

Find the value of tan(945°)​

Answer 1

Answer:

1

Step-by-step explanation:

tan 945* can be written as

tan (360+360+225)

which is nothing but tan 225

since Tan 225 can itself be written as Tan(180+45)

which is Tan180 + tan45

==>0+1

=1

Answer 2

Step-by-step explanation:

Given that : tan 945°

= tan ( 720°+225°)

= tan (2×360°+225°)

we know that tan (n ∙ 360° + θ) = tan θ

=tan (2×360°+225°)

=tan 225°

= tan (180°+45°)

we know that tan (180° + θ) = tan θ

tan (180°+45°)

=tan 45°

=1

therefore, tan945°=1
