Hello, there are two problems that I am stuck on. Any help will be appreciated thank you.
1. Explain why e^cos x < 3 for every real number x.
2. Explain why there does not exist a number theta such that: log cos(theta) = 0.1.
1. The exponent (that is cos x) is never larger than 1 ....
2. Assuming base 10, you have and it should be clear that .... By the way, a number theta does exist (in fact, an infinite number of values exist) but it's not real. The question should be worded as "Explain why there does not exist a real number theta such that: log cos(theta) = 0.1".
