This alternate definition is more useful, however, since you can use it to relate lengths of arcs to angles. The length of an arc is is the radius r times the angle Î¸ where the angle is measured in radians. For instance, an arc of Î¸ = 0.3 radians in a circle of radius r = 4 has length 0.3 times 4, that is, 1.2.
About 17 percent of men treated for low T receive testosterone injections every 7 to 22 days. Testosterone levels peak two to three days after the injection and then slowly drop until the next dose of the hormone is given. There are also testosterone patches that men can use. These patches can be placed on areas of the body such as the back, stomach, upper arm, or thigh.
Some men and women feel better when taking B12. Even though testosterone is suspended in oil and vitamin B12 is suspended in water, you can combine them into the same syringe to minimize the need for additional injections. Draw your testosterone dose into the syringe first, then draw the B12. If you are taking your testosterone once per week, you can add 0.5ml to 1ml of b12 to your injection. If you are splitting your testosterone injection into twice per week, try adding 0.25ml of b12.
