cot x = cos x / sin x
tan x = sin x / cos x
(Find common denominators)
cosx/sinx * cosx/cosx = cos^2x/sinxcosx
sinx/cosx * sinx/sinx = sin^2x/sinxcosx
(Now we can combine them)
csc / (sin^2x+cos^2x / sinxcosx)
(Simplify)
csc*sinx*cosx / sin^2x+cos^2x
sin^2x + cos^2x = 1
csc*sinx*cosx / (1)
csc*sinx*cosx
csc = 1/sinx
1/sinx*sinx = 1
(1)*cosx = cosx
Answer:
A and D sorry if i get it wrong.
Explanation:
Answer:
long fact(int n)
{
if(n<=1)//base case
return 1;
long p=fact(n-1);//recursive call.
return n*p;//returning the factorial.
}
Explanation:
Above written function is written in C++ language.It is a recursive function to find the factorial of the function.
If we enter a number equal to or less than 1 then the function returns 1. Then the recursive call is made and it is stored in the long variable p and the result is returned as n*p.
Breakers with adequate short-circuit must be installed in the panelboards.
<h3>What are these equipment about?</h3>
Common Overcurrent Protection Devices (OCPDs) are known to be Breakers or fuses that are often used to protect the full unit from too much current.
Note that Equipment such as switchboards and panelboards are often installed in an electrical system and they have to be of adequate measure of short-circuit current condition.
