If f(x)=4sinx/1+cosx then f'(x)=_____? I think that the derivative of 4sinx would be 4cos and cosx would be sinx but I don't know where to go from there.

find the derivative of f(x)=tanx-4/secx I used the quotient rule and got (sec^2x-4)(secx)-(tanx-4)(cosx)/sec^2x but I'm pretty sure that's wrong. Help. Thanks.

Write a program that prompts the user to enter a temperature, followed by a letter representing Celsius (C) or Fahrenheit (F). Then prompt the user for the conversion type and print the results to the screen with one decimal point. If the user enters a le...

This is what the program needs to do: Enter a temperature: 32.4 Enter 'C' for Celsius or 'F' for Fahrenheit: C Choose a conversion ('C' for Celsius or 'F' for Fahrenheit): F The temperature is: 90.3 F. How would I store the input when it asks for C or F,...

Okay, question. What if I inputted this: Enter a temperature: 32 Enter 'C' for Celsius or 'F' for Fahrenheit: c Choose a conversion ('C' for Celsius or 'F' for Fahrenheit): c The temperature is: 0.0 C. I want the program to read [The temperature is: 32 C....

How do you reprompt after the user inputs a wrong number into the program in C Programming? Loop structure? i.e. I want my code to do this: Enter a Compass Heading: 500.7 Please Input a Compass Heading between 0 and 360 Degrees. Enter a Compass Heading: 3...

Alright. I think I'm almost there. I'm just having a slight problem when I'm running the program. This is how it should look like (for reference). Enter a temperature: 32.4 Enter 'C' for Celsius or 'F' for Fahrenheit: C Choose a conversion ('C' for Celsiu...

Okay, so since my first switch statement is useless, how would I go about getting the program to only recognize F, f, C, and c only and if anything else than that is inputted for it to display "Invalid Syntax"?

16 years ago

Thanks! Now the first switch is working. But how do you end the program if the user inputs something else than C,c,F,f? It displays "Invalid Syntax" but it still moves onto the next line. I want it to just stop at "Invalid Syntax" if the user doesn't inpu...

Ok, I replaced the second switch with the code you provided earlier and now I got the second switch to operate correctly. I'm just wondering how to end the program if the user does not enter C,c, F, f.

Nevermind! I found out how to end the program if it's not C,c,f,F after experimenting. return(0); =]

We have just talked a little bit about loops structures. Haven't gotten into any coding with it though.

It doesn't close out the window. It just goes back to the ~> Now I just gotta figure out why my math is wrong since it's not spitting out the correct temperatures after the conversion.

Hmm, my F to C conversion works fine but my C to F is not giving me the right output. My code for C to F is (temp * 5/9) + 32. I think it's the way you divide the 5/9. Starting out with 32.4, when I do it a certain way on my calculator, I get 50, which th...

Oh! There's my problem. It's 9/5, not 5/9.

Yeah, at first I had the formulas in the wrong place, then I put 5/9 in one of the formulas instead of 9/5. Thanks for all your help man. I don't know what I would do without you. THANK YOU!!!

Yes, I have learned the if else statements. I made another switch statement within the first switch statement to account for the F to F and C to C and that did the trick. Thanks.

Ah! Thanks. When I was doing my if and while statements, I kept doing (heading < 0.0 || > 360.0) and kept wondering why it wasn't working. It needs to be while (heading <= 0.0 || heading > 360.0);
