SUMMARY

The discussion centers on the rules for combining and transforming trigonometric functions. The user expresses confusion regarding the addition, subtraction, multiplication, and division of these functions, particularly emphasizing the importance of having the same period, which is defined as 2π. The conversation highlights the need for clearer resources beyond the vague explanations found in the user's textbook. Participants suggest that understanding the foundational rules of trigonometry is essential for mastering these operations.

Trig Fuctions help! please

hi everyone,

my Trig textbook, is really vague and I'm not sure where i could find better information.

Basically, I'm not sure how to add, subtract, multiply, or divide trig functions. My text siad that to make a sinusoid the periods must be the same, and that the period is always 2 pi...? My book didn't even attempt to sauggest why--I'd really like to know what THE RULES FOR COMBINING AND TRANSFORMING TRIG FUNCTIONS ARE.

Thankyou to anyone who can send me in the right direction.

That's really a vague question. The rules for combining and transforming trig functions is the whole subject of 'trigonometry'. Can you be more specific?
