Question

Sinп/3×cosп/6- tgп/4

Answer 1

= sgrt3/2  * sgrt3/2 - 1= 3/4 - 1 = - 1/4 = -0,25

Answer 2

It seems like you want to evaluate the expression:

sin(π/3) * cos(π/6) - tan(π/4)

Let's break this down step by step:

1. First, calculate sin(π/3):

sin(π/3) = √3/2

2. Next, calculate cos(π/6):

cos(π/6) = √3/2

3. Now, calculate tan(π/4):

tan(π/4) = 1

Now, plug these values back into the original expression:

(√3/2) * (√3/2) - 1

Now, multiply the terms inside the parentheses:

(3/4) - 1

To subtract these fractions, you need a common denominator:

(3/4) - (4/4)

Now, subtract:

(3/4) - (4/4) = -1/4

So, the value of the expression sin(π/3) * cos(π/6) - tan(π/4) is -1/4.
