Answer 1

Думаю так, если кажется что не правильно лучше не списывай;)

Answer 2

To solve the equation 5cos^x - sin^(-4sin x) • cos x = 0, we can simplify it step by step:

1. Rewrite sin^(-4sin x) as 1/sin^(4sin x): 5cos^x - (1/sin^(4sin x)) • cos x = 0

2. Multiply both sides of the equation by sin^(4sin x): 5cos^x • sin^(4sin x) - cos x = 0

3. Multiply both sides of the equation by sin^x to get rid of the exponent: 5cos^x • sin^(5sin x) - sin x • cos x = 0

4. Rewrite sin^(5sin x) as (sin^x)^(5sin x): 5cos^x • (sin^x)^(5sin x) - sin x • cos x = 0

5. Let's substitute u = sin x: 5cos^x • (u^x)^(5u) - u • cos x = 0

Now, the equation is in terms of u. We can try to solve it numerically or graphically since there is no known algebraic solution.
