cos45 degrees multiplied by tan45 degrees, processing number 3 times tan30 degrees, minus 2 times, c

In the formula cos45xtan45+ 3xtan30-2cos60xsin45, since 30 degrees, 45 degrees, and 60 degrees are all special angles, cos45=sin45= 2 2, tan45=1, tan30=3 3, cos60=1 2.

Thus, the formula becomes 2 2x1+ 3x 3 3-2x1 2x 2 2. Simplify it and get 2 1 + 3 3-2 2x 2 2.

After calculation, we get 3-2-2.

So, the value of cos45xtan45 + 3xtan30-2cos60xsin45 is 3-2 2.

sin30 = 1 2 sin45 = two-thirds, two-thirds, six-six, three-thirds, sin90 = 1

tan30 = three tan45 = 1 tan60 = two-thirds three tan90 meaning.

cos30 = two-thirds, three, cos45 = two-thirds, two-thirds, two-cos60 = 1, 2, cos90 = 0

sin45 tan30-tan60 + cos45 * cos30 = root number 2 2 (root number 3 3) - root number 3 + root number 2 2 * root number 3 2 = root number 3 root number 2 - root number 3 + root number 6 4

Root number 6 2 - root number 3 + root number 6 4

3 4 * root number 6 - root number 3

sin45 tan30-tan60 + cos45 * cos30 = root number 2 2 (root number 3 3) - root number 3 + root number 2 2 * root number 3 2 = root number 3 root number 2 - root number 3 + root number 6 4
