Whats the difference between tan35/65 and tan(35/65)?

Question

I get different answers when i plug them into my calculator. How do i know when to use parantheses?

Answer 1

Dear Soriya,

 

I will not go through answer, instead I will talk on how the input data is interpreted.

 

A compiler on Calculator device or on computer's calculator will consider  "tan35/65" as "( tan(35) )/ 65" as no brackets provided in input data.

 

While in case of tan(35/65) it will be considered as ( tan ( (35) / (65) ) which will end up with different answer.

 

Always keep BDMAS rule in mind while working with an equation

 

(B) Bracket, (D) Division, (M) Multiplication, (A) Addition, (S) Subtraction

 

Thank,

Raj

Hello Soriya.

tan35/65 will give you (tan35)/65, it will calculate tangent of 35 then divide by 65.

tan(35/65) will give you tan(35/65), it will divide 35 by 65 then give you the tangent of that.
