36 cos^2 [10] - 96 cos^2 [10] + 64 cos^2 [10] how to simplify this one ?
36 cos^2 [10] - 96 cos^2 [10] + 64 cos^2 [10]
Notice that we can factor out cos^2 (10) from every term and we're left with :
cos^2 (10) * [ 36 - 96 + 64] =
cos^2 (10) * [ 4] =
4* [cos (10)]^2 =
about 3.879
Sry ! it seems i mistyped the power of the cos a little bit, can you please help me again ?
36 cos^2 [10] - 96 cos^4 [10] + 64 cos^6 [10]
Thx !
Figured it out just now it was supposed to be factor in the form of
[6cos 10 - 8 cos^3 10]^2
Thx for your response !
