2^sinx+2^cosx find the minimum value of this trignometry

Anit [1.1K]

Take the deritiivive
$ln(2)cos(x)2^{sin(x)}-ln(2)sin(x)2^{cos(x)}$
it is zero at pi/4 and it repeats at every pi
minimum at where slope goesfrom negative to positive
so at 5pi/4 and 13pi/4 so at every 2pi interval

evaluate origial at 5pi/4
$2^{sin(5pi/4)}+2^{cos(5pi/4)}$ =
$(2^ \frac{- \sqrt{2} }{2} )+(2^ \frac{- \sqrt{2} }{2} )$ =
$2(2^ \frac{- \sqrt{2} }{2} )$ or aprox 1.22509

An 8 by 19 ft wall has three 4 by 5ft windows. The area of three windows is what percent of the area of the entire wall

sergij07 [2.7K]

Area of the wall = 8 x 19 = 152 ft square
Area of the window = 4 x 5 = 20 ft square
Area of 3 windows = 20 x 3 = 60 ft square
The percent area of 3 windows from area of the wall = 60/152 or approximately .395 or 39.5%
