Need to solve this : |coshyperbolic[0,003894+0,021918imaginary]|/|coshyperbolic((0,003894+0,021918)| any ideas ?
 
Don't really understand the question
Has your class not yet covered "functions" or "function notation"? Are you not familiar with what a hyperbolic cosine actually is? Have you heard of the natural exponential (being the number "e", which is the base of what is called the "natural logarithm")?

We'll be glad to try to find lesson links, so you can get caught up to the question, but it would be helpful to know which parts are causing the confusion. Thank you! ;)
