Powers of trigonometric functions are rewritten to be useful in calculus. Verify the identity. (Simplify your answers completely.) $2 \sin^4(x) + 2 \cos^4(x) = 2 - 4 \cos^2(x) + 4 \cos^4(x)$ $2 \sin^4(x) + 2 \cos^4(x) = 2(\sin^2(x))(\quad) + \cos^4(x)$ $= 2(1 - \cos^2(x))(1 - \cos^2(x)) + \quad$ $= 2 - 4 \cos^2(x) + 4 \cos^4(x)$

Use the following information to answer the next two questions. To study the effect of grazing on biodiversity in a grassland community, scientists prevented sheep and rabbits from accessing a particular area of the grassland. They discovered that biodiversity decreased in areas where grazing did not occur because grazing prevents the most successful plant species from overtaking an area. When grazers consume successful plant species, some of the less successful plant species are given a chance to grow. 30. Plant species that consistently remain in the grassland community where grazing is prevented are known as a. seral species b climax species c. pioneer species d. intermediate species 31. Grazing increases biodiversity in a grassland by decreasing the a. gene flow of less successful plant species b. genetic drift of more successful plant species c. interspecific competition for less successful plant species d. interspecific competition for more successful plant species
