lcd display to answer of sin(36.4)....?

[elmayadunna]

how can we get lcd display answer of sin(36.4)?plz help me.....

i want to display sin(36.4),cos(42.6) using mikroc.plz help me code to this.

If you want to disply numbers like 34.6 then you need to convert it to string using

Code C - [expand]

float floatval = 0.0;
unsigned char myString[23];
 
floatval = 36.456546;
FloatToStr(floatval, myString);
LCD_Out(1,1,myString);

function. If you want to plot the graph of the values then you need GLCD.

thank you for ur kind attention.now i want to find the answer for d.

d=sin(u)*sin(v)/((sin(v)*cos(u))+(sin(u)*cos(v)));

in here u & v value maybe point value.like u & v =34.6,76.8,32.7.......

i want to code above equation using mikroc.plz help me.

 

[jayanth.devarayanadurga]

What you have written itself is the code.

 

[elmayadunna]

What you have written itself is the code.

plz tell me how can write it?i haven't no any idea how to write above equation?

hi replace the u and v by above variables fu and fv, and also include math.h...

 

[nick703]

as per jayanth mentioned try your long equation to sort form calculate sin , cos in form of u ,v and put that value in your real equation and get desired value . and also make sure that venkadesh mentioned in your function u,v is not declared
so first make your program and if any error in output then post your code..

[naya2013]

this mikroc code helpful we also.but there is a error.

float fu = motor;
float fv=motor;

 

[nick703]

motor = put your value like 36.4 so motor is constant in this code.
