Find l eat cos bt
WebWe first need to find L {cos bt}. We can use the cosine law to find L {cos bt}: L {cos bt} = cos (bt) + sin (bt) Best Match Video Recommendation: Solved by verified expert We … WebStep 1: Multiply the given function, i.e. f (t) by e^ {-st}, where s is a complex number such that s = x + iy Step 2; Integrate this product with respect to the time (t) by taking limits as 0 and ∞. This process results in Laplace transformation of f (t), and is denoted by F (s). What is the Laplace method?
