y=7cos^2(-3)

y = 7 cos^{2} (- 3)

y = 7 cos^{2} (3)

Decimal Notation

y = 6.86059 \dots

Solution steps

y = 7 cos^{2} (- 3)

cos^{2} (- 3) = cos^{2} (3)

cos^{2} (- 3)

Simplify

cos (- 3) : cos (3)

cos (- 3)

Use the following property:

cos (- x) = cos (x)

cos (- 3) = cos (3)

= cos (3)

= cos^{2} (3)

y = 7 cos^{2} (3)

cos (22 0^{\circ}) = \frac{a}{3}

c, 1 f = 3 cos (x) - 4 sec (x) + 3

y = cos^{215} (0) - sin^{215} (0)

sin (6 0^{\circ}) = (\frac{x}{81})

d = 7.2 sec (\cdot sin (3 0^{\circ} - 2 0^{\circ}))
