Question

tan45°+cos45°-sin45°​

Answer 1

Answer:

1

Step-by-step explanation:

1+1/√2-1/√2

=1 answer

Answer 2

Step-by-step explanation:

tan 45°=1

cos 45°=1/sqrt 2

sin 45°=1/sqrt 2

Therefore,

1+(1/root2)+(1/root2)

According to BODMAS rule,

= {(root2 +1)/root 2} - 1/ root 2

= (root 2)/ (root 2)

= 1
