Answer 1

Respuesta:

3) 3

4) √2

Explicación paso a paso:

3)

tan45 = 1/1 = 1

sec45 = √2/1 = √2

tan³45 + sec²45

1³ + √2²

1 + 2

3

4)

cot45 = 1/1 = 1

sen45 = 1/√2

[tex]\frac{sec45}{cot45}.\frac{cot45}{sen45.\sqrt{2}}[/tex]

[tex]\frac{\sqrt{2}}{1}.\frac{1}{\frac{1}{\sqrt{2}}.\sqrt{2}}[/tex]

[tex]\sqrt{2}.\frac{1}{1}[/tex]

[tex]\sqrt{2}.1[/tex]

[tex]\sqrt{2}[/tex]
