A = (f(x) âf(a)) /(x â a), 'A' represents the average slope. Here (x-a) is used to represent the change in input values and f(x) â f(a) is used to denote the change in output of the function f(x). Step 3: Now we will choose any random values for variables 'x' and 'a'.
Depending on the grade, pulled muscles can take one to eight weeks to heal. For the first 72 hours, apply ice, use elevation and, in consultation with a doctor, take anti-inflammatory medication. After 72 hours, use hot packs to bring blood into the muscle and provide nourishment, which accelerates healing. Massage or physical therapy can hasten the healing process.
The vast majority of pulled calf muscles will heal completely within a few weeks without any treatment. Pulled muscles are also called muscle strains. They occur when muscle fibers are stretched beyond their normal length. The injury creates tears in the muscle that are usually tiny (microtears). In the most severe calf muscle strains, the entire muscle is torn, causing significant swelling and pain.
