Divide both sides by cos[x]
<span>You get 1 = Tan[x] </span>
<span>Tan[x] = 1 where x = 45 degrees {+ integer multiples of 180 degrees due to periodicity of tan} </span>
<span>x = 45 + 180*k OR Pi/4 + kPi, for k any integer</span>
Answer:
1,436.03
Step-by-step explanation:
V=4/3*pi*r^3
V=4/3*3.14*7^3
V=1,436.03
We can replace sin x with x anywhere in the limit as long as x approaches 0.
Also,
I will make the assumption that <span>log(x)=ln(x)</span><span>.
The limit result can be proven if the base of </span><span>log(x)</span><span> is 10.
</span>
We get the indeterminate form 0/0, so we have to use <span>Lhopitals rule
</span>
<span>
Therefore,
</span>
